I am replacing a raid array with a new larger one. After finishing the
migration, I try to mount the new one where the old one was located. This
doesn't work due to something stale in systemd.
There is also a bug in mount, as it should at least return a failure
when this happens. So there are actually 2 bugs here.
The package is util-linux because that is what `ubuntu-bug mount` chose.
