[Cooker] NFS problems

[Guillaume Rousse]

My server can't accepts any NFS mount request since today. Every attempt
fails with following mesage:
rpc.mountd: authenticated mount request...
rpc.mountd: getfh failed: operation not permitted
I didn't modify anything prior to this. I attemped upgrading latest
nfs-utils, kernel and initscript, but nothing changed.
Any clue ?
