- update to v14:
* mkosi now creates distro~release subdirectories inside the build, cache
and output directories for each distro~release combination that is
built. This allows building for multiple distros without throwing away
the results of a previous distro build every time.
* The preferred names for mkosi configuration files and directories are
now mkosi.conf and mkosi.conf.d/ respectively. The old names
(mkosi.default and mkosi.default.d) have been removed from the docs but
are still supported for backwards compatibility.
* plain_squashfs type images will now also be named with a .raw suffix.
* tar type images will now respect the --compress option.
* Pacman's SigLevel option was changed to use the same default value as
used on Arch which is SigLevel = Required DatabaseOptional. If this
results in keyring errors, you need to update the keyring by running
* Support for CentOS 7 was dropped. If you still need to support CentOS 7,
we recommend using any mkosi version up to 13.
* Support for BIOS/grub was dropped. because EFI hardware is widely
available and legacy BIOS systems do not support the feature set to
fully verify a boot chain from firmware to userland and it has become
bothersome to maintain for little use.
* To generate BIOS images you can use any version of mkosi up to mkosi 13
or the new --bios-size option. This can be used to add a BIOS boot
partition of the specified size on which grub (or any other bootloader)
can be installed with the help of mkosi's script support (depending on
your needs most likely mkosi.postinst or mkosi.finalize). This method
can also be used for other EFI bootloaders that mkosi intentionally does
not support.
* mkosi now unconditionally copies the kernel, initrd and kernel cmdline
from the image that were previously only copied out for Qemu boot.
* mkosi now runs apt and dpkg on the host. As such, we now require apt and
