I'd rather adjust systemd and leave fstab stable than vice-versa.
Here's an interesting fact: What systemd does (in this situation)
isn't true automounting; rather it waits for the *first* time the
device/volume becomes available, and then mounts it. Any later
attachments of the volume do not cause mounting (until the next
But at this point, I only need to investigate the issue. The
documentation I've managed to find about systemd is rather abstract,
there's no map between specific bits of functionality and the files
that control them.
My understanding is that everything systemd does is controlled by
"units". In this case, entries in fstab cause the creation of units
based on a "template". If you could point me to the template file in
question, it would probably point me to all of the things I need to
