To me this sounds like a chicken and an egg problem. It
both depends and provides this at the same time :/. But
hey, if it's supposed to work then OK.

depended on locking.
Except for the fact that to be able to mount anything RW you
generally _want_ to have locks. And can't have locks without the mount. Not that it wouldn't work, it's just that I would
not do it [for obvious reasons].

You just need to be careful to set it up correctly in the initrd: either
make sure that you mount the root partition as 'nolock' or else make
sure that you mount /var/lib/nfs, and start rpc.statd before you start
init and any other applications that might need locking.


The nfsmount which is in the klibc distribution supports running an ad hoc portmap daemon, which allows locking to be done by forwarding information to the "real" portmap for when the real rpc.statd is run.
