If I recall it correctly, it retries a mount attempt that fails after
something like 1min (which seems like a long time when you are waiting
for it;-). I think that was done so that clients don't flood a rebooting
server with mount attempts, but that code was written long, long ago.

ps: I just reviewed and thanked Bjoern for the -vers= patch.
