Public bug reported:

With different linux distros the systemd-run based mount of a Quobyte
volume can fail. This is connected to the --user option causing issues
with privilege escalation. Log example:

Mar 19 09:09:27 manualnovaci nova-compute[20516]: ERROR nova.compute.manager [instance: 6ffe17b6-9706-48d2-9ca5-73a670889a19] ProcessExecutionError: Unexpected error while running command.

Besides this the current systemd check is erroneous due to whitespace in
path.
