OK, you've piqued my curiousity. :-)

What about it seems to be troublesome?

From the writeup here:

<www.ubuntu.com/.../serveredition>

it would seem a better choice than, say, CentOS, and given that I've
had only good experiences with Ubuntu's desktop editions I'm preparing
to download/install it this weekend and would like to know what to keep
an eye on.

Anything you can cite would be useful, and I'll specifically check those
things out and report back next week. Thanks!
