BreadBoard goes into production next week.
Had some problems with the SSL patch I put into Squid, so I'm reworking that. Also, postfix and squid seemed to get in each other's way a bit, so I'm not running the both on the same box any more. Also had to do some hacking around the ISC DHCP client's resolv.conf creating stuff for one box, which has given me some more ideas for things that need to be configurable (ie, listen to bits of DHCP config or not).
A belated thank-you to John Baldwin and Paul Saab for making the PXE loader stuff in FreeBSD work, and for putting up with me pestering them about it. =)
