Please remove dmraid from the Ubuntu archive

[Lukas Märdian]

It got dropped from Debian due to being obsolete and dead upstream. An alternative seems to be "mdadm".

We're still tracking it in Ubuntu "main" as part of the live-common seed and an Ubiquity Recommends.
The Ubiquity installer is depecrated, though. So we should consider dropping dmraid from main.

currently the idea is for ubiquity to not be in main for 24.04. There is a very high chance that this will succeed
It might still be around for the flavors, but it should be in universe then

"""
for subiquity installers I expect that dmraid is obsolete, and that we are covered by the mdadm usage.

for ubiquity, there are still references to dmraid in partman.

d-i seems to have undergone a pruning step to remove dmraid support with commits such as https://salsa.debian.org/installer-team/partman-base/-/commit/72735280fefab7e27acb4bbb1b6b83cb88f75611

I guess the idea is to get Ubiquity and dmraid demoted to universe, before 24.04 is released.

[Lukas Märdian (slyon)]

We might also consider disabling dmraid functionality in Ubiquitiy, and deleting dmraid from the archive. To avoid dragging obsolete packages around.

Please cross check with the subiquity folks that this is *actually* obsolete. The last I knew, it implemented support for firmware-assisted software raid systems that were not supported by mdadm.
