My thinking here is that, unless network mounts in fstab are listed as
'nofail', that netmount failing due to the dependent services not
being able to start would be a valid case.  Sysadmins that don't want
netmount to fail no matter what would be able to use 'nofail' to
ensure that happens.

This is of course predicated on (1) it being a good idea, and (2)
fstabinfo or whatever the check currently is that would add nfsclient
to depend() could easily swap 'use' for 'need' based on the (lack of)
existence of the nofail attribute in fstab.
