If you don't have "quiet" on the kernel cmdline you should see pairs of
"Starting ..." and "Started ... " lines. If a service fails you'll see
"Starting... " and "Starting ... failed" instead. The "failed" is
highlighted red.

Hmm, so if the restart is triggered by the user this will already work
correctly, but it currently won't if this is an automatic restart due to
a service aborting. I have now added this to the TODO list.

Add Wants=fsck@%i.service or similar to the unit file.

For now, it's probably easiert to use fstab.

You can have multiple targets. You first boot into the first target, do
what you want to do, finally start the second target.
