FAI with NFS v4 on Debian Wheezy

[Toomas Tamm]

Hello!

I think I got it the other (incorrect) way in my original post. Sorry!
In wheezy, "FQDN minus hostname" is the default (Domain is not set
in /etc/idmapd.conf by default), while in squeeze, it is fixed to
"localdomain" in the provided /etc/idmapd.conf.

The bottom line is, one must ensure that the domain is identical on the
server and client. Otherwise strange things happen with UIDs and GIDs.
