It's called "layers", in this case. HARDWIRED TERMINALS IN THE KERNEL, FOR GHOD'S SAKE? See above for the size of a good, sane SVR2 kernel. I've hacked quite a bit into this system. In user mode. It's not quite 4BSD yet, but then we have no need for networking. (To the people who will immediately compare this posting to my posting asking for system load help and say "Aha!": Wrong. It's 18 users running RM/COBOL and/or UNIFY that brings tdi2 to its knees.) ++Brandon -- ``for is he not of the Children of Luthien?
