i did a pile of testing, not including running 8.12.x on my production
machines for at least a year. so far it seems all i missed when i
updated was tweaking the afterboot instructions to point out that you
need to start an smtp listener to get local mail delivered.

okay, so the smtp listener will do that. that's academic.

right. as has been established. you need to fix your dns so that the
name of 127.0.0.1 isn't localhost.citi.umich.edu.
