OK. The host.conf problem was the problem. I'm now getting RPC
timeouts on the thing I'm trying to boot because I'm not running
portmapper or bootparamd. Go figure :-). At least RARP is out of the
way now.
Still no idea on the overflows I was seeing, but I'm not seeing them
now, so it does look like it was due to the bfp buffer chopping things
badly maybe? Something to think about.
Bill, since you seem to be keeper of rarpd, you might want to add a
note in the man page about this... Also, the following diffs look
like they may be useful. They add sysloging for cases that don't
already have it.
Thanks for your helpful hint!
Warner
