[Beowulf] SuSE 9.3

We've been a CentOS shop since version 3.0 and haven't looked back.  The
fact that they offer update support for 5 years allows us more
flexibility in planning our upgrades.  I've noticed that a lot of people
on the fedora front do the "every other release" upgrade cycle which
probably works out perfectly, as support for each release is continued
up until the second subsequent release.  It is then transfered to
FedoraLegacy, so you don't really lose support altogether (though my
experience with them for earlier RH distros wasn't that inspiring).

Basically, the choice is yours.  FC2 was really impressive, but it is
also getting up there in age, mostly because of Fedora's rapid release
cycle and is, I believe, being transfered to Fedora Legacy already.  You
should always take that into consideration.

But in any case, good luck with your build.
