Management techiniques for multiple FreeBSD servers?

[Howard Jones]

Hi,

I'm looking around for any articles/docs regarding techniques for
managing groups of FreeBSD servers - things like running a local package
mirror or build server, standardised installs, update management - all
the usual boring stuff. I know that people like Yahoo use thousands of
*BSD systems, but does anyone have any pointers on tools to make
day-to-day management of them scale?

Best Regards,

Howie
