That's true. I'll give it a try. I believe GNU chroot does not change the
current directory.

The sh and perl executables are both present, so I think it's more likely
something to do with what you said above.

Actually, I untar'red the base system to /dos/linux, and I'm just trying to
remove a few unnecessary packages which aren't needed in an extremely stripped
down system running from umsdos.

Thanks for the help.
