backport ubuntu-core-installer code to noble

[Michael Hudson-Doyle]

I added code in oracular to build an installer for UC24. We would like to (slightly) productionize this installer and so building on a noble base would be better.

[test plan]
We should build a livefs with a command like:

$ start-livefs-build --livefs=~mwhudson/+livefs/ubuntu/noble/test --arch=amd64 --pocket proposed --project ubuntu-core-installer

[regression potential]
looking at the change that has already been merged to git:

https://git.launchpad.net/livecd-rootfs/commit/?id=0df4234c281a1496269740422f22d5306ec12edc

It is clear that the risk of compromising other builds is negligible and indeed the same code did not when landed in devel. The ubuntu-core-installer project also builds successfully on oracular and should build fine in noble too -- but that would not be a regression!

Hello Michael, or anyone else affected,

Accepted livecd-rootfs into noble-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/livecd-rootfs/24.04.75 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-noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-noble. 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.

I built a livefs (https://launchpad.net/~mwhudson/+livefs/ubuntu/noble/test/+build/667772) and it built fine. I made it into an ISO and that revealed that we need some subiquity changes in the ubuntu/noble branch as well but that's not a problem with the livecd-rootfs changes.

I also built a desktop (https://launchpad.net/~mwhudson/+livefs/ubuntu/noble/test/+build/668142) and server (https://launchpad.net/~mwhudson/+livefs/ubuntu/noble/test/+build/668143) livefs. The server build failed but that is true for the current livecd-rootfs in updates as well -- so I think this is verified enough.
