>Description:
If you:
> su
# cd /dev
# MAKEDEV pass4
You only get /dev/pass0 - /dev/pass3; I noticed this because tosha
wouldn't access my cdrom drive.
>How-To-Repeat:
>Fix:
UNTESTED!
Change the CAM passthrough code in MAKEDEV from:
while [ $i -lt $units ]; do
to
while [ $i -le $units ]; do
As I understand what's going on, this is the Right Thing.
