Use a minimal initrd to switch to the full initrd stored in /usr
...
The growth of binaries over time and the inclusion of new features
filled the available boot partition space, so that the kernel+initrd
almost couldn't fit twice anymore as required for updates. We employed
workarounds such as wrapper scripts for ignition, afterburn and other
binaries so that they are loaded from /usr. However, this was still not
enough and we would have to do the same for (network) kernel modules and
firmware. To avoid making this ever more complex we can use a dedicated
initrd focused on loading the full initrd from /usr and then this full
initrd can use dracut as before and even drop all the workarounds we
accumulated.
Generate a minimal initrd to use instead of the full bootengine initrd.
The bootengine initrd gets stored as squashfs on /usr. The minimal
initrd still includes the early_cpio for amd64 microcode updates.
We have a fixed list of modules or module directories to include, only
focused on loading /usr and any emergency console interaction. This
requires also checking for module dependencies to copy over.
The busybox, veritysetup, and kmod binaries are needed and get their
required libraries resolved and copied over. They are not static and
use shared libraries which should be ok for now. The resulting vmlinuz
file is 27 MB for amd64, down from ~60 MB, so we have enough room to
include more kernel modules and so on for the next years while we also
grow the boot partition and wait for users to redeploy until we can rely
on a larger boot partition and eventually drop the minimal initrd again.
Pulls in https://github.com/flatcar/bootengine/pull/110 for the
minimal initrd script and https://github.com/flatcar/seismograph/pull/12
for making the device mapper discovery for the "rootdev" command more
reliable.
This also requied a backport of a kernel patch from 2017 that exposes
the PARTUUID in the /sys uevent file.

ci-automation/release.sh: Fix upload to R2
...
The upload to R2 was added experimentally and we now want to make use of
it. The CHANNEL variable wasn't defined and it failed because of that.
Do the upload for all channels and set the variable up first. Existing
releases should get synced from the current Origin server via a FUSE
mount that we anyway want to rely on for the directory listing that
Caddy creates. Left to decide is how we manage the "current" version
but that is done manually anyway as of now.
