As a brief follow-up to this, I'm in the process of moving 2 RH8/Samba
3.0.x servers to 2 new FC3/Samba 3.0.1x servers, users, groups,
printers, roaming profiles, samba tdb files, cups printers, etc.. I've
seen several people ask how to do this on the list, so I'm starting a
"how-to" that I'll post to the list for corrections, changes, etc..
Just thought it'd be useful. Figured since I can't code, I can help
with documentation. Of course, I'll see how the move goes for me before
posting a "how-to" to the list.
