Public bug reported:

preseeding with the 6.12 kernel fails due to apparmor feature mismatch.

[ Impact ]

preseeding with that kernel fails which makes the boot slower.

[ Test Plan ]

* build image with livecd-rootfs
* register image on cloud
* boot image
* check that "snap debug seeding" output doesn't contain the "seed-restart-system-key" key.

[ Where problems could occur ]

Very unlikely that this creates problems. We backported similar changes
a couple of times already.

[ Other Info ]
* this only needs to be SRUed for Noble . The relevant code is already in plucky and oracular
* a similar SRU we did already is https://bugs.launchpad.net/ubuntu/+source/livecd-rootfs/+bug/2098306

** Affects: livecd-rootfs (Ubuntu)
