fai-setup: (1) all_squash,anonuid=500,anongid=500 (2) exportfs -r

[Shaul Karl]

  Just wondering why not having fai-setup

(1) use all_squash,anonuid=500,anongid=500, or some other uid and gid
    both for $FAI_CONFIGDIR and $NFSROOT when exporting those
    directories.
(2) use exportfs -r instead of guessing which nfs server is running and
    restarting it.
