The userdata partition is mounted under /usr/local/data. It is and will stay
read-write and its purpose is to store userdata like config, secure-storage.
--fixed-size produce a partition of the right size but doesn't expand
the filesystem. Instead we use --size --extra-space and
--overhead-factor to have a fixed size partition and fixed size
filesystem
We are now using efibootguard to provide a A/B boot path for
the kernel and the rootfs.
This commit remove some change for systemd/systemd-boot that are
not needed anymore and rework how we set the command line, as we
will need to have the command line argument of the kernel both
inside do_image_wic and in a future do_image_swu
