minimized cloud image policy, introduced in version 23.10.16, is to not install recommends for any package
installs during build. This is to keep the image as small as possible. This also extends to
the grub related packages.
This solves the problems detailed in LP: #2037075 and aligns other arches more with amd64 install of
grub/shim packages for both minimized and non minimized ubuntu-cpc cloud image builds.
When trying to make changes to refactor livecd-rootfs, it is difficult to
know what side effects a change may have because of the use of globs on
arch/subarch and the lack of an authoritative list of supported arch
combinations.
This assembles a list of all possible values for $ARCH:$SUBARCH by looking at
all existing uses of $SUBARCH in live-build/auto/config and combining with
etc/default-arches from ubuntu-cdimage:
$ grep + etc/default-arches |grep -vE '(trusty|xenial|bionic|focal)[[:space:]]|appliance'
It also includes a special-case *appliance* glob, because there are many
Ubuntu Core appliance builds and there may be more in the future, and we
don't want to have to update livecd-rootfs with a hard-coded list.
Otherwise, this includes all currently used / supported combinations. The
amd64+kassel subarch is referenced in the code, but stopped being built a
while ago because "end of contract"; and there are some older no-longer-used
subarchs for particular raspi variants, which there is work to clean up
separately. So this should be a no-op wrt buildability of any existing
images on mantic - and if not, that's important for us to know!
With the introduction of the 6.5 kernel for mantic on 13th September ago we are seeing image build failures
on the armhf builds. The build failure was `No kernel output for generic-lpae!`.
Introduced in the 6.4 kernel and therefore now also in 6.5 there is no generic-lpae flavor anymore. it's just generic now.
As such this commit updates the expected flavour for armhf to generic.
minimize-manual takes an argument of the path to the chroot but of the 3 commands that are run the argument
is only used twice and with the third hardcoding "chroot" as the path to the chroot.
Thankfully "chroot" has been the patch passed in for the current uses of minimize-manual but this
could cause issues later if that were to change.
This commit resolves the problem preventing future issues.
