[Bug 1913314] Re: The subiquity server images do not offer the hwe kernel variant

[Łukasz Zemczak]

Built an ubuntu-server-live image with PROPOSED=1 via cdimage. The
resulting livefs build seems correct:

https://launchpad.net/~ubuntu-cdimage/+livefs/ubuntu/focal/ubuntu-
server-live/+build/257451

Files resulting from this build:
    livecd.ubuntu-server.initrd-generic (80.0 MiB)
    livecd.ubuntu-server.initrd-generic-hwe (83.6 MiB)
    livecd.ubuntu-server.installer.squashfs (233.2 MiB)
    livecd.ubuntu-server.kernel-generic (11.1 MiB)
    livecd.ubuntu-server.kernel-generic-hwe (9.3 MiB)
    livecd.ubuntu-server.manifest (15.5 KiB)
    livecd.ubuntu-server.modules.squashfs-generic (57.1 MiB)
    livecd.ubuntu-server.modules.squashfs-generic-hwe (59.4 MiB)
    livecd.ubuntu-server.rootfs.tar.gz (402.1 MiB)
    livecd.ubuntu-server.squashfs (356.7 MiB)
    livecd.ubuntu-server.squashfs.manifest (15.5 KiB)

As seen, the build now results in both GA and HWE kernels present.
Looking at the build logs, I have confirmed that the correct livecd-
rootfs version was used (2.664.13). Ready for release.

Title:
  The subiquity server images do not offer the hwe kernel variant

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

Bug description:
  [Impact]

  For 20.04.2 we need to offer both the GA and HWE kernels in our
  ubuntu-server images, which currently is not the case as we missed the
  step of enabling both ga and hwe kernel variants in livecd-rootfs.
  This is required for 20.04.2.

  [Test Case]

  Start a -proposed enabled livefs ubuntu-server-live focal build (can be a build via cdimage as well). Make sure that the livefs build results in two sets of kernel+initrd pairs.
  If tested via cdimage, additionally it might be good to check the actual image if HWE is selectable.

  [Where problems can occur]

  The change is self-contained only to the ubuntu-server-live image
  paths, so the only places where issues can occur is in kernel
  selection for the images. No other possibilities.
