Remember when Linux had a layer to run x86 BSD binaries? Now freebsd
can run linux binaries instead. I think it was called iBCS back in
the day.

Yes: intel defined a standard mechanism, which everyone did variations
on. It was therefor to put in an "interpreter" for different OSs, where
interpreter meant the code that interprets systems calls and dispatched
them. I remember looking over Drew's shoulder at the code for SCO
binaries. Solaris 86 had an interpreter for Linux, Linux an interpreter
for Solaris 86.
