This is as dirty as mounting is for now (hardcoded partition).

This is required so that the overlayfs partition is changed to p5 instead of p6, since the rauc partition was removed.

This pre-init removes one unneeded step, and avoids the messy long line at the end of the script.

This reverts commit ba2192b.

This pre-init removes one unneeded setp, and avoids the messy long line at the end of the script.

This adds a pre-init script that is ran before systemd. This scripts prepares the system so that the rootfs will be left unaltered, but combine it with a writable ext4 filesystem, where data can be stored into. Both rootfs use the same overlay, which makes it possible to preserve data while overriding the rootfs during an upgrade.
