Yes (and that's what the man page says, so I knew that.)

That's what I want. Start on all boots regardless, and before any 
"remote" fs in fstab. I.e. before attempting to mount any "local" nfs 
mount in fstab.

But a user who tried that says the "local" nfs mount(s) in his 
/etc/fstab still failed. I tried it as well with an f19 guest vm and got 
the same results, namely that the nfs mount(s) failed to mount at boot.
