Just ufs2, nothing fancy like nullfs.  There was an nfsv3 fs mounted
(my home directory) but /usr/src, /usr/obj, and /usr/ports are all
local ufs2 fs, all mounted with softupdates.

I had no unusual kernel compile options, other than
KDB/DDB/BREAK_TO_DEBUGGER (eg, no witness, no invariants).

This is an "AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ (2009.27-MHz K8-class CPU)"
and a UDMA133 ATA disk.  Nothing very exotic...
