On the one hand, we're starting to roll it out... *only* on new servers,
and the servers we're rolling it out on are *only* fileservers - a couple
attached to RAID boxes, and the other two will be attached to RAIDs, but
server home directories.

I feel that I'd stay with 6.x unless there's a must-have feature. Right
now, I'm playing with stuff on those servers - for one, NetworkMangler is
*extremely* noisy, and trying to find *full* examples of its configuration
file... I've only found *tiny* bits and pieces. I think I got it to log
only errors, but the startup was *noisy*, and the documentation leaves
something to be desired.

Oh, and it enables wireless. On a server. With no wifi. And I don't see
any ifcfg-'s to set them to *off*.

I really don't like this "we'll do everything" attitude, esp. when
"everything" is intended for users of laptops....

And the install, as I think I posted last week, was nasty - if I want
anything other than it's "let me partition *and* throw LVM on top", it
goes to choose disks... and selects *ALL* by default.

So there's a bunch of stuff I don't like, and will wait to see if they fix
