mknod device numbers

[Milo Velimirovic 31 Wing 785-8030]

Hi,
 All of this is very installation specific. The major/minor numbers in the
device inodes need to correspond exactly to the entries in the devtab
structure in the kernel. This is probably something that can be divined by
running nm on the kernel, /unix ? (All this is from memory,  my annotated V6
kernel listing is buried at home right now.) But, I'd be surprised to see a V6
distribution that didn't have the rk drivers built in. Another thing to
watch out for is the rk driver, er, device names/numbers that interleaved a
file system across multiple drives.   


BTW, is there anywhere one can get a "legal license" to run V6, V7, 2.XBSD on  
my pdp11/34's and 11/44?
