Title:
  Apparmor profile policy permstable32 component is missing in Jammy 6.8
  kernel

Status in livecd-rootfs package in Ubuntu:
  Invalid
Status in livecd-rootfs source package in Jammy:
  Fix Committed
Status in livecd-rootfs source package in Noble:
  Fix Committed

Bug description:
  A CPC snap preseeding test on recent Jammy image build with 6.8 kernel.
  Jammy 6.8 kernel has additional component under policy:permstable32 and this is missing in 6.8 apparmor directly.

  [ Impact ]

  Boot will be slowed by ~200ms until this is resolved in livecd-rootfs

  [ Test Plan ]
  * Build a jammy cloud image with preseeded snaps with missing components under `permstable32` file
  * Boot an instance
  * Run `snap debug preseed`
  * Confirm there is nothing in seed-restart-system-key when running `snap debug preseeding` command

  [ Where problems could occur ]
  * Missing these components, images with 6.8 kernel will not be optimized for first boot deployments.

  [ Other Info ]
