Thanks a lot for the hint, that seems to have fixed it for me as well. I
was previously looking over the changelog too but couldn't relate any of
the entries to my issue successfully. Double-checking whatever I was
doing might have helped my case as well. :)

Like you, I won't be absolutely sure before at least 24h of testing have
passed, but so far there hasn't been a single undesirable spinup of my
backup disk for the last couple of hours. As mentioned before, my disk
wouldn't stay quiet for more than 25 minutes.

For whom it may concern: I'm running Ubuntu Gutsy and did a backport of
nfs-utils 1.1.1-12ubuntu3, currently contained in Hardy.
