Hmm.. I tried that and it didn't seem to work.
The disklabel change was successful, but growfs didn't seem to
expand the root partition any.. df(1) still shows it as 50M.
I ran growfs after booting single user mode but before mounting
any disks.. perhaps that caused it to not work.
Since that didn't work, I booted a 4.7-REL fixit floppy and tried
to run growfs from there, but then that growfs core dumped:
Program terminated with signal 11, Segmentation fault.

2335 setbit(cg_clustersfree(&acg), block);

2330 return;
2331 }

2335 setbit(cg_clustersfree(&acg), block);

Notice "block=-874" which indicates something is weird or corrupted.
So now I've got extra space in the partition which (apparently) is
not being used and I can't seem to get at it (see below).
Plus I have a sneaking suspicion that I've screwed up something,
but there's nothing in the growfs man page that indicates what I
did was wrong.
FYI, this is a test machine so it's OK if it gets hosed.
