- Update to version 39:
+ New systemd-cgtop tool to show control groups by their resource
usage.
+ Linking against libacl for ACLs is optional again.
+ If a group "adm" exists, journal files are automatically owned
by them, thus allow members of this group full access to the
system journal as well as all user journals.
+ The journal now stores the SELinux context of the logging
client for all entries.
+ Add C++ inclusion guards to all public headers.
+ New output mode "cat" in the journal to print only text
messages, without any meta data like date or time.
+ Include tiny X server wrapper as a temporary stop-gap to teach
XOrg udev display enumeration (until XOrg supports udev
hotplugging for display devices).
+ Add new systemd-cat tool for executing arbitrary programs with
STDERR/STDOUT connected to the journal. Can also act as BSD
logger replacement, and does so by default.
+ Optionally store all locally generated coredumps in the journal
along with meta data.
+ systemd-tmpfiles learnt four new commands: n, L, c, b, for
writing short strings to files (for usage for /sys), and for
creating symlinks, character and block device nodes.
+ New unit file option ControlGroupPersistent= to make cgroups
persistent.
+ Support multiple local RTCs in a sane way.
+ No longer monopolize IO when replaying readahead data on
rotating disks.
+ Don't show kernel threads in systemd-cgls anymore, unless
requested with new -k switch. (forwarded request 101496 from fcrozat)
