I hadn't had a chance to test it... this one (attached) works (I had
forgotten to update the index commands in the hd[i-j] and hd[k-l])

anything on an "even" device (hdb, hdd, hdf, hdh, hdj, hdl, etc) is a
slave. the "odd" ones (hda, hdc, etc) are masters

Actually, the kernel doesn't need the /dev files... user-space programs
(fdisk, for instance, possibly mkraid too, not sure) need them as an
interface to the devices in the kernel... devfs may make this picture
clearer down the road... or muddier :)

MAKEDEV is historically bad about keeping up with devices.txt, so
it's fairly common... those mknod's I gave last time should work too

MAKEDEV is a decent shell script, although it's just glorified
mknod wrapping when it comes down to it :)
reading devices.txt and a mknod --help is about all that can be done
for understanding the /dev entries... as to major/minor and why they're
still around, "historical cruft" is about it for now.
