Hi,

I've noticed that there's no rc script for configuring vnode disks. IMHO,
vnds are similar to swap partitions - not fish, not flesh. However,
vnds are related to mounting and I think it's useful that you can put
them into ``critical_mount_local'' in your /etc/rc.conf. Otherwise,
it would be hard to figure out at which level vnconfig should happen.
Therefore, I've wrote a little pseudo mount_vnd as a shell script. The
syntax for a fstab-entry is straight-forward:

<vnode_disk> <regular_file> vnd <params>

<vnode_disk> is e.g., /dev/vnd0 or vnd0
<regular_file> is the file that contains the image
<params> contains the normal flags for vnconfig. For flags that need
a parameter use "-t=3Dblah" instead of the normal "-t blah".  I've added
the flag -g which takes the geometry for the disk as parameter. Also
note that the flags -F, -l and -l are ignored because I see no sense
in using them in this context.

Use with caution, it's NOT fool-proof!
