>Description:
twed is not supported by vinum. The first thing is that on stable
we need to define every device with its major number in vinumio.c.
The other is that commands.c checks for "vinum start" during boot
if the device is of type DEVSTAT_TYPE_DIRECT, but does not allow
DEVSTAT_TYPE_STORARRAY.
As vinum could be used to mirror two Raid 5 arrays, or just for
an easier disk management, DEVSTAT_TYPE_STORARRAY should also
be allowed here.
>How-To-Repeat:
Try to install vinum on a twed-device, eg /dev/twed1a.
>Fix:
Apply the following changes:
