According the changelog, 2019-11-27 entry says "07:13 dereckson: Disk drives look corrupted. Attach a new 1 To drive to the machine. Install a clean CentOS 7 on this drive to recover data."

Per T1592, we're now on CentOS 8, and as Dwellers is the Docker development and staging server, we're going to use CentOS 8 stream.

Server has been reprovisionned, there is still to apply highstate, and review pending Dwellers Maniphest tasks.

Errors to fix
