Bah. Add a prerequisites field to fstab with all the filesystems that 
must be mounted before that one can be mounted.

Then just teach mountlocal and mountremote to iterate mounting until no 
new filesystems can be mounted.

Maybe we should add a "remote" flag to fstab, and make the rc.d script 
read fstab itself instead of relying on mount to know which filesystems 
are local and which are remote. The rc.d scripts can then extract that 
info and benefit from it in two ways:

1) It will know which filesystems can be mounted before network, and 
which require network.
2) The filesystems themselves could be used in BEFORE or REQUIRE.

Mmmmmm.

Either rcorder gets taught about this improved fstab, or we would have 
to add a program that reads fstab and then generates rc.d scripts as 
appropriate. Not sure I like the latter, but it has the advantage of 
keeping rcorder simple.

Just food for thought.
