Comment 1 for bug 2034606

Investigated, results as follows:

* lunar live-server is fine
* lunar with main branch subiquity is also fine, so I don't think we've regressed something here
* the oldest mantic live-server I have, 20230801, is also broken
* force installing multipath-tools 0.8.8, by rebuilding for mantic + adjusting the build number higher results in a somewhat working system (mdadm messages: "no arrays found in config or automatically") but does produce a `multipath -l` result

Unclear to me yet if this is outright a regression in the archive or if curtin needs to do something differently for mantic.

Any debugging suggestions for the failed boot scenario?
