System: NetBSD sun-lamp.pc.cs.cmu.edu 1.0A NetBSD 1.0A (SUN_LAMP) #0: Sun Jun 18 16:41:02 EDT 1995 firstname.lastname@example.org:/usr/src/sys/arch/i386/compile/SUN_LAMP i386
FS unmounting/'clean' code can cause system to crash on reboot,
and can leave file systems incorrectly marked 'clean.'
This is probably the cause of some of the hangs on reboot
that people have been reporting.
cd /usr/src/sbin/init ; make ; make install ; reboot
note crash and/or trouble rebooting. on reboot:
note that fsck says that root file system is clean. then:
note that root file system (MARKED CLEAN!!!) was actually dirty.
Dunno; if i'd had time to track it down, i would have.
