[Bug 1052264] Re: nfsd won't start unless exports has content

[pdf]

I can't see from the changelogs what this was meant to fix, but users
already have methods of disabling nfsd if they don't want it to start,
so this change in behaviour doesn't seem to be necessary, and breaks
expected behaviour.

I can see two ways of solving this, either by simply deleting the  `grep
-q '^[[:space:]]*[^#]*/' $export_files` test (preferable since it
restores expected behaviour), or by introducing an additional switch in
/etc/default/nfs-kernel-server to control whether nfsd is started with
empty exports (this could default to on to restore expected behaviour,
but this still seems superfluous, since the user can simply disable the
init job using existing mechanisms).
