You think the master builds are done on a machine that is identical to yours at home?
Obviously not, but that doesn't have any bearing on what I said.
Build a -stable release on a same platform faster machine. Now unpack the .tgz files on the target machines, copy in /bsd, /bsd.rd, reboot. ta-da, patched machine. None of your configuration is touched by this process.
Maybe I'm unclear on what building -stable actually does. Correct me if I'm wrong, but "world" encompasses a lot more than just the kernel and ramdisk, right? Simply replacing just those two alone isn't fully keeping on top of things.
