A preface first:

Lots of love for Gentoo, it seems :-)

I'm now positive in pushing a full-fledged Gentoo infrastructure in my
office (complete with Gentoo maintenance support VMs)

And, as I promised, I'll publish your stories in my blog (currently
undergoing migration from b2evo to TikiWiki).

to several mysql database servers, xen cluster with livemigration, ietd
iscsi targets, apache webserver, radius, postfix mailservers with pop3 and
imap postboxes for several hundred  clients and syslog server.

That depends on what Kai meant with "uptime". Maybe he meant the VMs (he's
using Xen, after all) never needs a restart, but the BIND service still gets
regular update and the consequent service-restart.

Xen or XenServer? Well, they're both Xen, anyways :-)

In my office I use XenServer, and Gentoo VMs on Xen(Server) truly are the
epitomes of stability. I had had 2 'U' servers froze after restart, 1 'A'
server went wacky after installing a package, and a 'D' server consuming CPU
for reasons unknown.

(Well, one Gentoo server indeed consumed CPU, too, but not surprising since
it's the gateway/firewall handling 5 (five!) WAN connections)

keeping software up to date can keep you busy for some time but I assume
that this is not different to any other distri.

Indeed! It's a battle trying to get other distro's to have a local support
infra.

How I wish I can do that :-(

Currently I'm forced to use Windows on the workstation because there are
some custom-made apps that can run only on Windows... *sigh*
