If you have been a member of the team, you should have seen LKP on SCO UNIX.
LKP is different from lxrun as it does not simply catch syscalls via signals 
but creates a Linux infrastructure under /linux. Linux programs run chroot()ed
in /linux and can see the UNIX infrastructure under /unix.

For this reason, it is easy to have the "right" things in /proc and /etc.

BTW: my information is from people who have been in the team or have been very 
close to the team.
