I would hope so. :)

Centrally logging the builders is probably unnecessary. Especially if
we're bouncing them all the time.

Sure - but I'm thinking of the emergency "oh look at that nightmare"

Collectd - off. We're not gaining much by having that punish the syslog
We can monitor the builders w/o needing all of the copious info that
fas I'm not very worried about - though I suspect a couple of things
will change w/how we get the dbs onto the hosts.

okay - but I think that's more something for the kojidevs than fedora

So one thing I'm not sure I understand - why would we need so many arm
builders? Is it b/c there are so many more arm archs so there will need
to be more pkgs built?
