...or at least touch a subset of them, to make their NFS domain the same 
as the 'other' set's DNS default. *sigh*

Also: It's the wrong list to ask this on, but would you happen to have 
any pointers on getting this NFS-domain configuration working on CentOS 
or similar machines?  I can find nothing intermediate between the RFC 
and the nfsidmap tool & idmap.conf manpages.  Doing the obvious 
configuration doesn't work, and even the debugging syslog messages give 
few clues about what, precisely, is wrong.

Even the wiki [1] is... thin.
