If the NFS server is up and running:

$ initctl list | grep nfs
nfs-kernel-nfsd start/running
nfs-kernel-mountd start/running, process 12281
nfs-kernel-statd start/running, process 11580
nfs-kernel-exports start/running

Then the following causes nfsd and mountd to bail out:

$ restart nfs-kernel-exports

$ initctl list | grep nfs
nfs-kernel-nfsd stop/waiting
nfs-kernel-mountd stop/waiting
nfs-kernel-statd start/running, process 11580
nfs-kernel-exports start/running

So they have to be manually restarted:

$ start nfs-kernel-mountd
$ start nfs-kernel-nfsd

This is probably because the Upstart “start on” only triggers during startup.

I hope the svn change r31103 fixed this.

I made more changes, because I still had problems at boot. I think after r31119 it works for me in all situations.
