[Bug 443321] Re: drbd devices not automatically mounted via /etc/fstab even witn _netdev

The process of mounting DRBD devices is a bit complex. Something like
this should be achieved:

network started -> drbd service started -> drbd devices synced -> server
becomes (drbd) primary -> mount drbd device

I understand Ari's idea and have to think about it for a bit. Ari's
suggestion doesn't guarante that DRBD will be mountable; it's missing a
step - DRBD becoming primary. I understand that this works for him, but
we have to consider implications on secondary node, which won't be
primary and will also try mouting device (if we ship something like this
by default). Will mountnfs then fail and give up mounting all other
network filesystems? And, if mountnfs is started before drbd devices are
synced, mounting drbd devices wil fail.

I don't think we can cover all use cases of drbd. Drbd with some kind of
cluster manager is probably most common use case.
