Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

you can replace /var/lib/nfs by a sombolic link to a directory inside your 
drbd filesystem. Then switching over to standby node is possible without 
remounting filesystems from nfs clients. Depending on used hardware it 
could also be necessary to provide as fsid in /etc/exports.
