Wes had a better answer than I. Another thing I can think of is TCP mounts for NFS. BSD/OS has them as well, but I'm pretty sure that most System V's don't, and I'm not sure about Linux. > Another question I had was versions of BSDI, Linux, and SCO can the various > versions of FreeBSD emulate.

All recent versions of FreeBSD support BSD/OS 2.x a.out files. There are some problems with 1.x. In fact, the problems are more between 1.x and 2.x than BSD/OS and FreeBSD; there were some differences in the structures used for file locking. You may, however, find that some BSD/386 1.x executables die on you before ever getting to main(). What we still don't have is support for BSD/OS 3.0 elf binaries. I think they're working on it, though. Greg
