Fix read-only rootfs setup /wrt etc overlay - and more
v3 cover Fix read-only rootfs setup /wrt etc overlay - and more
Changes in v3:
- create DEPLOY_DIR_IMAGE paths when needed in image-uuid and squashfs classes
- drop not longer needed image_do_mounts from image-uuid
Changes in v2:
- panic on /var mounting failure during overlay setup
- panic-reboot on initramfs failures in secure mode
- /root persistence
- faster rootfs selection under dm-verity
This addresses the problem of current read-only rootfs + /etc overlay as used for the SWUpdate setups.
Due to ordering issues in systemd startup between machine-id handling vs. making /etc writable via the overlay, various things are broken down the line, e.g. journal reporting. Reading [1], it appeared to be best to move the overlay mounting into the initramfs. And this implementation proves this to be right: simpler and working smoothly.
As a by-product, this also unifies the initramfs-abrootfs-hook, and makes it simpler as well.
Furthermore, this plugs a hole in the secure boot process if the initramfs fails (we got a shell then), makes /root persistent and optimizes the rootfs selection via dm-verity.

PATCH v3 2/7 initramfs-abrootfs-hook: Convert to an initramfs-class recipe
In reply to Jan KiszkaFrom: Jan Kiszka <[email protected]>
This unifies the pattern we generate initramfs images for non-secure and secure SWUpdate images. Besides cleaning up the related abrootfs selection hook, the unification is a precondition for adding another initramfs recipe later that will be shared between both image types
The pattern followed in the new initramfs-abrootfs-hook script is now similar to initramfs-verity-hook: a local-top hook is used, rather than a patch for Debian's local script. This hook looks for the matching rootfs by read-only mounting candidates, comparing the contained UUID against the one stored in the initramfs, unmounting again, and then setting the ROOT variable on match.

PATCH v3 4/7 Convert /etc overlay from systemd mount unit to initramfs hook
In reply to Jan KiszkaFrom: Jan Kiszka <[email protected]>
As systemd is not well prepared for read-only rootfs, specifically /wrt machine-id management and anything that depends on it, it's best to mount the /etc overlay already in the initramfs. This implies that also /var is mounted at that level. We still keep the fstab setup done by wic-swu-img class so that systemd will recognize the rootfs as read-only and not try to remount it rw which will only fail with underlying squashfs.
