I finally got a good snapshot out of my Sun 3/60 yesterday, from Apr 16
sources. I booted the new kernel, and then did another "make build" with
DESTDIR=/ to replace all the userland binaries. After that was done,
"reboot":

syncing disks... 14 14 11 6 done
uvn_io: note: size check fired
panic: unmount: dangling vnode
Stopped in reboot at  _Debugger+0x6: unlk a6
db>

I'm willing to bet this is because /sbin/init got replaced. Is this such an
evil corner case that we can't handle it cleanly? Just FYI, when rebooted,
the system came up with no troubles at all (not even any fsck complaints).
