I tried building a release on -current a few weeks back, three 
days into the compile I could no longer log into my machine, and rebooting 
it could not get me into single user because it couldn't find /bin/sh. The 
best part is I had it reading the source, writing the files and writing 
the build log all to an NFS mounted file system. So how my local file 
system got wrecked only leads to me having been hacked via the OpenSSH 
server included with 1.6 or something seriously wrong with 1.6 and/or NFS. 
The only files that should have been being writtin on the local disk were 
to /tmp and /var/mail. None of that makes sense. I still have a copy of 
the build log, and the reason the build failed was because it all the 
sudden just started getting permission denied errors when trying to use 
ln. Probes to mountd on the pmax machine were unresponsive, the NFS server 
is a Pentium 4 running NetBSD 1.6K/i386.

	Any ideas?
