This update introduces the explicit Dependencies= setting, instead
of relying on implicit dependencies via alphanumerical ordering.
We also take the opportunity to rename the "final" preset to the
"system" preset, which seems like a better name.
Currently, we install the systemd install tree in the base image and
then build the initrd and final images from the base image. This means
if that any systemd package is pulled in during the initrd or final
image builds, it will override our version.
To fix this, we stop installing our build of systemd in the base image,
and store it in the output directory instead. That allows us to refer to
it using ExtraTrees= in the final and initrd image builds to install it
after all the distro packages have been installed, ensuring our version
always takes priority.
vsock should work properly after the latest release of mkosi. But
to make sure it works, let's exit with 123 in case of success and
check for that in Github Actions.
Files placed in /EFI/Linux/UKI.efi.extra.d/ and /loader/addons/ are
opened and verified using the LoadImage protocol, and will thus get
verified via shim/firmware.
If they are valid signed PE files, the .cmdline section will be
extracted and appended. If there are multiple addons in each directory,
they will be parsed in alphanumerical order.
Optionally the .uname sections are also matched if present, so
that they can be used to filter out addons as well if needed, and only
addons that correspond exactly to the UKI being loaded are used.
It is recommended to also always add a .sbat section to addons, so
that they can be mass-revoked with just a policy update.
The files must have a .addon.efi suffix.
Files in the per-UKI directory are parsed, sorted, measured and
appended first. Then, files in the generic directory are processed.
We ship with empty /var, so /var/log/journal does not exist, which
means journald does not do persistent logging. Let's fix that by
setting the config to explicitly enable persistent logging.
This accidentally got pulled into a commit even though it was only
for local testing, let's drop it again so we correctly use erofs
when building local images.
We currently have to resort to SSH to get more than one interactive
terminal in a mkosi qemu VM. Let's increase our options by installing
tmux in the final image, which can multiplex the serial console into
many unique terminal sessions.
Let's start moving towards a more involved partitioning setup to
test our stuff more when using mkosi.
The root partition is generated on boot with systemd-repart.
CentOS supports neither erofs nor btrfs so we use squashfs and xfs
instead.
We also enable SecureBoot= locally for additional coverage. This
and the use of verity means users need to run `mkosi genkey` once
to generate the keys necessary to do secure boot and verity.
If we're making a /usr only image, we still want to populate /etc
fully on first boot. To make that possible, let's copy /etc to
/usr/share/factory/mkosi in a finalize script, which runs after
all changes to the image have been made. Let's also add a tmpfiles
snippet that merges /usr/share/factory/mkosi with /etc on boot to
populate /etc.
Instead of building the initrds for the mkosi images with dracut,
let's switch to using mkosi presets to build the initrd with mkosi
as well.
This commit splits up our single image build into three separate
mkosi presets:
1. The "base" preset. This image contains systemd and all its runtime
dependencies. The sole purpose of this image is to serve as a base image
for the initrd and the final image. It's also responsible for building
systemd from source with the build script. The results are installed into
the base image. Note that we install the systemd and udev packages into this
image as well to prevent package managers from overriding the systemd we built
from source with the distro packaged systemd if it's pulled in as a dependency
by another package from the initrd or final profiles.
2. The "initrd" preset. This image provides the initrd. It's trivial and does
nothing more than packaging the base image up as a zstd compressed initramfs and
adds /init and /etc/initrd-release symlinks to the image.
3. The "final" preset. This image builds on top of the base image and adds
a kernel and extra packages that are useful for testing and debugging.
We also split out the optional kernel build into a separate set of config files
that are only included if a kernel to build is actually provided.
Note that this commit doesn't really change anything about how mkosi is used.
The commands remain the same, except that mkosi will now build all the presets
in order. "mkosi summary" will show the summary of all the presets. "mkosi qemu,
boot, shell" will always boot the final preset. With "-f", all presets will be
built and the final one is booted. "-i" makes a cache of each preset.
The only thing to keep in mind is that specifying config via the mkosi CLI will
apply to each of the presets. e.g. any extra packages added with "-p" will be
installed in both the initrd and the final image. To apply local configuration
to a single preset, create a file 00-local.conf in
mkosi.presets/<profile>/mkosi.conf.d and put all the preset specific configuration
in there.
