@iainlane doesn't work on Ubuntu infrastructure anymore, and `bionic` is still ESM, but not really supported anymore either.
`noble`, which is the latest Ubuntu, probably is better for testing `systemd` in 2024, and pinging `qa-help` on IRC is the current official way to contact the team behind Ubuntu's infrastructure.
This reverts commit 5e8ff010a1.
This broke all the URLs, we can't have that. (And actually, we probably don't
_want_ to make the change either. It's nicer to have all the pages in one
directory, so one doesn't have to figure out to which collection the page
belongs.)
