[Bug 1896755] Re: Backport snap-preseed work from groovy to focal

[Timo Aaltonen]

Hello Dimitri, or anyone else affected,

Accepted livecd-rootfs into focal-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/livecd-
rootfs/2.664.8 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: livecd-rootfs (Ubuntu Focal)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-focal

Title:
  Backport snap-preseed work from groovy to focal

Status in livecd-rootfs package in Ubuntu:
  Fix Released
Status in livecd-rootfs source package in Focal:
  Fix Committed
Status in livecd-rootfs source package in Groovy:
  Fix Released

Bug description:
  [Impact]

   * livecd-rootfs when building classic images with snaps preseeded
  doesn't perform any first-boot tasks during image building. It means
  fist boot is computationally intensive. In groovy, livecd-rootfs
  gained ability to precompute snap seeding, apparmor profiles making
  first boot snap seeding a lot faster. Backport the goodies.

  [Test Case]

   * Perform stock build of ubuntu-cpc lxd or qcow cloud image

   * Boot and observe they complete boot, and perfrom snap seeding very
  quickly (i.e. less than a couple of seconds)

  [Regression Potential]

   * Images might fail to build, or be missbuilt. However, these changes
  have been tested on groovy with the same snapd across all SKUs. Thus
  only groovy-vs-focal incompatibilities may arise.
