I really don't want to edit the shell script. I'd like to leave the
distribution alone. Plus, matlab does this trick to support multiple
architectures. You should be able to export this directory and use it on
multiple machines, including multiple NetBSD-emulating-another-OS

I guess having a "matlab" script in NetBSD's /usr/local/bin which calls
the emulated one using the Linux or ULTRIX sh would work.

But I think it'd be really nice if this just worked right, out of the box.

I.E. set up NetBSD, populate /emul/Old_OS, mount the old usr on
/emul/OldOS/usr, and you're set. Oh well.

Take care,
