The files
http://minnie.tuhs.org/UnixTree/V7/usr/sys/dev/rl.c
http://minnie.tuhs.org/UnixTree/V7/usr/sys/conf/mkconf.c
don't seem to match - mkconf.c wants to generate references to
rlopen() and rlclose(), which don't exist in that version of rl.
What I'm really looking for is the right version of driver(s) etc.
It seems that a version of the rl driver that matches
mkconf, was never supplied by the bell labs.
As a workaround delete the rl entry in cdevsw and the line
"int rlopen,..." from c.c. This will give you a block device of the rl disk,
but no raw device.
