Yeah... don't really need that. :)
In vinum's case there's a directory /dev/vinum/drive that points
to the device backing the vinum device:
/dev/vinum % ls -lR
total 7

lrwxr-xr-x 1 root wheel 11 Sep 26 1999 vinumdrive1 -> /dev/da2s1e
Ok, now is there a way to get rid of these symlinks when vinum goes
away? Ok, if there isn't a way to delete them, what if I unload
and reload vinum then try to make them again?
