Oops. This was a thoroughly successful commit, wasn't it? At least
it didn't break `make world'.
I'll think out another way and test more thoroughly. How does this
look?
if [ -f /etc/vinumslices ]; then
read /etc/vinumslices
if [ -r /modules/vinum.ko ]; then # jkh paranoia
kldload vinum
vinum read $vinum_slices
else
echo "Can't find /modules/vinum.ko"
fi

OK, I take that back. You can also tell me about your successes :-)
There's still one way you can shoot yourself in the foot with
statically configured Vinum: unless you specify VINUMDEBUG, you can
find yourself out of sync with Vinum(8): they pass structures via
ioctl, and some of the structures include debugging information.
