Subject: [PATCH] Rewrite of startup code:

vinum_read:
  Accept 0 parameters, hand an empty string to the kernel if so.
  Use new ioctl VINUM_READCONFIG, not VINUM_CREATE, to read config.

vinum_start: When passed 0 parameters, drop the devstat kludge and
     call vinum_read instead.  It's no longer necessary to distinguish
     between "start" and "read" if no parameters are passed, and
     probably one of them should go away.
