There's a few things we could do on fas load:
a) add more fas servers.
b) reduce the number of runs. How often do we change someone in
sysadmin-noc, sysadmin-main, sysadmin-build?
c) move to a system where we only re-run fasClient when there is a
I'd agree collectd off probibly. Or at least a seperate one if we
needed to monitor them.

Yeah, we could hopefully have another network thats larger than /24 for
the arm builders.
I'm sure some of this will be a process of 'oh no, what we have now
doesn't scale, lets fix it'. Of course some of it we can get ready for
up front too.
Overall I like the idea of the automated builder re-install and think
it will get us more ready for things like a large arm cluster.
