[sorry in digest mode here with some cut and paste action, I have very
small chunks of time to reply to beowulf these days]


However, not for nothing, that reputation sure as hell is big enough IMHO :)

(as a pre p.s. :  Hi Tim!!)


So anyway, just recently at the advice from some of our Sr. sysadmins,
we started out over here in the other Cambridge with this thing called
puppet, in our HPC environment...

http://reductivelabs.com/trac/puppet/

It has a few issues at 6600+ cpu, they still have some "puppet master"
issues. However, nothing that can't be overcome.  All I know is that
it seems to "just work" (tm) for a pretty large multi site cross
campus and beyond cluster installation.  We do do what I like to call
"puppet lite", just bits of the OS and config (lsf/ssh/nagios etc)
rather than the whole shebang...

The OS is still a traditional DHCP/PXE bootstrap.

As always YMMV... and more often than not, it certainly will!

Best,

j.
