Unix program on Linux question

[Brian Densmore]

Ok, I answered my own question.

There are two possible interfaces that allow Unix binaries 
to run on Linux. The iBCS for Linux 2.2 kernels and the Linux ABI
for 2.4 kernels. There does seem to be some limitation and some
Unices require certain shared (proprietary) libraries to be available.
It looks as though UnixWare may be ok though.

Thanks for the pointers.

Brian
