                       Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.)  You can apply it to
your programs, too.

When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and
modification follow.

GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

<one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version.

This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

You should have received a copy of the GNU General Public License along
    with this program; if not, write to the Free Software Foundation, Inc.,
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

Gnomovision version 69, Copyright (C) year name of author
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary.  Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  `Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

================================================

Combustion is a minimal module for dracut, which runs a user provided script on
the first boot of a system.

You can use this to create additional files, install packages, set up devices 
or even re-partition the hard disk. The configuration can be provided as a
shell script, loaded from an external storage media and is run during boot in a 
new system snapshot. On success, the system will directly boot into that new
snapshot, so that no reboot is needed.

Installation
------------

Run `make install` to install it manually. Usually combustion is packaged up
and installed during image builds already.

How to use it
-------------

The configuration files are copied from a filesystem with the LABEL
"combustion", but to be compatible and co-installable with ignition
(https://github.com/coreos/ignition), the LABEL "ignition" is used as fallback.
All-uppercase labels are accepted as well. Alternatively, if a KIWI selfinstall
.iso is used for deployment (LABEL "INSTALL"), this is used as a fallback.

It expects a directory "combustion" at the root level of the filesystem and
a file "script" inside, which is executed inside a transactional-update shell.

```
 <root directory>
 ├── combustion
 │   ├── script
 │   └── ... other files
 └── ignition (optional)
     └── config.ign
```

If a QEMU fw_cfg blob with the name "opt/org.opensuse.combustion/script" is
found, it is preferred and the content of that is used as script.
Example parameter for QEMU:
-fw_cfg name=opt/org.opensuse.combustion/script,file=/var/combustion-script

You can do everything necessary for initial system configuration from this
script, including addition of ssh keys, adding users, changing passwords
or even doing partitioning changes.

Simple example
--------------

Example for formatting a USB drive and adding a config, which installs the
"vim-small" package and creates a /root/welcome file:

```bash
mkfs.ext4 /dev/sdX
e2label /dev/sdX ignition
mount /dev/sdX /mnt
mkdir -p /mnt/combustion/
cat >/mnt/combustion/script <<EOF
#!/bin/sh
# combustion: network
systemctl enable sshd.service
zypper --non-interactive install vim-small
cp welcome /root/welcome
EOF
echo "Hello User!" >/mnt/combustion/welcome
umount /mnt
```

The `# combustion: network` comment triggers networking initialization before
running the script. This is equivalent to passing "rd.neednet=1" on the kernel
cmdline and so the network configuration parameters (man dracut.cmdline) apply
here as well. If those aren't specified, it defaults to "ip=dhcp" for each
available interface.

More complex configuration example
----------------------------------

This script additionally provides visible feedback during boot, sets a password
and copies a public ssh key (which has to be in the "combustion" folder).

```bash
#!/bin/bash
# combustion: network
# Redirect output to the console
exec > >(exec tee -a /dev/tty0) 2>&1
# Set a password for root, generate the hash with "openssl passwd -6"
echo 'root:$5$.wn2BZHlEJ5R3B1C$TAHEchlU.h2tvfOpOki54NaHpGYKwdNhjaBuSpDotD7' | chpasswd -e
# Add a public ssh key and enable sshd
mkdir -pm700 /root/.ssh/
cat id_rsa_new.pub >> /root/.ssh/authorized_keys
systemctl enable sshd.service
# Install vim-small
zypper --non-interactive install vim-small
# Leave a marker
echo "Configured with combustion" > /etc/issue.d/combustion
```

Perform modifications in the initrd environment
-----------------------------------------------

Using the `# combustion: prepare` marker, the initrd environment can be modified
for instance to perform tasks before `/sysroot` is mounted or to write
NetworkManager connection configuration into
`/etc/NetworkManager/system-connections/`. If the marker is present, the script
is invoked with `--prepare` as parameter from `combustion-prepare.service`, in
addition to the main invocation inside the transaction later.
Example:

```bash
#!/bin/bash
# combustion: network prepare
set -euxo pipefail

nm_config() {
    umask 077 # Required for NM config
    mkdir -p /etc/NetworkManager/system-connections/
    cat >/etc/NetworkManager/system-connections/static.nmconnection <<-EOF
    [connection]
    id=static
    type=ethernet
    autoconnect=true

[ipv4]
    method=manual
    dns=192.168.100.1
    address1=192.168.100.42/24,192.168.100.1
EOF
}

if [ "${1-}" = "--prepare" ]; then
    nm_config # Configure NM in the initrd
    exit 0
fi

# Redirect output to the console
exec > >(exec tee -a /dev/tty0) 2>&1

nm_config # Configure NM in the system
curl example.com
# Leave a marker
echo "Configured with combustion" > /etc/issue.d/combustion

How it works
------------

### Firstboot detection

Combustion ships a `firstboot` dracut module which introduces `firstboot.target`
as well as a `firstboot-detect.service`. This service mounts `/sysroot/etc`
early in the initrd (in a private namespace, to not trigger `.mount` units and
dependencies out of order). It then checks for the following conditions:

* `combustion.firstboot` or `ignition.firstboot` are present on the kernel
cmdline
* `/etc/machine-id` does not exist in `/sysroot`. Note: Unlike systemd's
`ConditionFirstBoot`, this is not triggered by "uninitialized" in the
machine-id file or influcenced by `systemd.firstboot=` on the kernel cmdline.

If one of them applies, it enables and starts `firstboot.target`. It's
important that all units started by `firstboot.target` are effectively
ordered after `firstboot-detect.service` to prevent loops. Add some Before=
to `firstboot-detect.service` if necessary.

If any of the firstboot configuration mechanisms (combustion, ignition)
find a user specified config, they delete `/var/lib/YaST2/reconfig_system`.
The result is that if (and only if) no configuration for those was provided,
the file still exists in the real system and triggers interactive setup
(jeos-firstboot, YaST Firstboot) if present.

The final system eventually reaches `first-boot-complete.target` and after that
`systemd-machine-id-commit.service`, which commits `/etc/machine-id` to disk and
thus `firstboot-detect.service` no longer triggers `firstboot.target` on
subsequent boots.

### Combustion

The `combustion` dracut module is included by default, but omitted if dracut is
run on an already configured system in `hostonly` mode.

`firstboot.target` pulls in `combustion.service` and
`combustion-prepare.service`. The latter runs after the config drive or
QEMU fw_cfg blob appears (see `combustion.rules` for details). The combustion
configuration is copied from the config source into `/dev/shm/combustion/config`
(this is accessible in `transactional-update shell` later). If the script
contains the `prepare` flag, it's executed now with the `--prepare` option. If
the `network` flag is present, networking is enabled in the initrd. After
`/sysroot` is mounted and network is up (if enabled), `combustion.service` runs,
which tries to activate all mountpoints in the system's /etc/fstab and then
calls transactional-update in a chroot.

In this transactional-update session the script is started and the exit code
recorded. If the script failed, transactional-update rollback is called and
combustion.service marked as failed, which causes booting to fail. Note that a
missing config drive or script is not considered a fatal error and only results
in a warning.

/sysroot is unmounted and mounted again, so that the default subvolume gets
reevaluated and directly booted into.

Now, `initrd-parse-etc.service` can evaluate the final `/sysroot/etc/fstab` and
create the matching `sysroot-FOO.mount` units which are started before switching
into the root filesystem.
