Was the original Lions book different to the officially published version
I picked up on Amazon?
Mine explicitly doesn't include hardware drivers, eg. for the RK
disk packs, other than a sample driver, with a comment (presumably
from Lions) basically saying that such things weren't as interesting. It
also doesn't include much (if any? has been a while since I looked at
it) userland source code.
It is still a wonderful, educational book, though.

I'm not certain, but pretty sure the original and later published ones were the
same material.
