%description
A fancy wrapper around "dnf --installroot", "apt", "pacman", and "zypper" that
generates disk images with a number of bells and whistles.

Generated images are tailored to the purpose: GPT partitions,
systemd-boot or grub2, images for containers, VMs, initrd, and extensions.

mkosi can boot an image via QEMU or systemd-nspawn, or simply start a shell in
chroot, burn the image to a device, connect to a running VM via ssh, extract
logs and coredumps, and also serve an image over HTTP.

See https://mkosi.systemd.io/ for documentation.

%package initrd
Summary:        Build initrds locally using mkosi
Requires:       %{name} = %{version}-%{release}
Requires:       coreutils
Requires:       (%{name}-initrd-tukit if read-only-root-fs)

%description initrd
This package provides the mkosi-initrd wrapper to build initrds with mkosi
locally.

%package initrd-tukit
Summary:        Build initrds locally using mkosi with transactional updates
Requires:       %{name} = %{version}-%{release}
Requires:       read-only-root-fs

%description initrd-tukit
mkosi calls bwrap, and that does not work with transactional updates, so this
package provides a special mkosi-initrd wrapper to support building initrds on
transactional systems.

%posttrans initrd-tukit
# mkosi runs in a sandbox, and for that purpose it relies on bubblewrap. The
# problem is transactional-update chroots to a snapshot, and bubblewrap does not
# work there because it requires pivot_root:
# https://github.com/containers/bubblewrap/issues/135
# The issue is quite old, there is even a PR trying to fall back to chroot if
# pivot_root fails (https://github.com/containers/bubblewrap/pull/595), but
# apparently bubblewrap upstream is not trying to fix this.
# The workaround implemented in mkosi-initrd-chroot.sh was proposed by the main
# mkosi upstream maintainer:
# https://github.com/containers/bubblewrap/issues/592#issuecomment-2243087731
