...lerned a lot from it about Linux and Plan9. I would never
have started it by myself. What Russ left in his contrib had done the
trick (catching syscalls with a note handler)... and was well 
structured and easy for me to understand. From that, it was
easy to extend and implement further syscalls. So thanks Russ!

linuxemu is just one binary. The linux-part is the porblem :-)
I had started a script that tars a binary and all its dependencies into
a tarball. And an rc-script that can be cat'ed at the top of the tar to
make it executable (unpacks/build the linux-namespace and 
some config-files/run).

see:

But i'm not sure if that is the right way todo it. The best would be just
some directory where all the linux lives in and maybe some script that
downloads/installs packages from some major linux distrio in it.

By the way:
Linuxemu has some limitation so that you cant use the TLS versions of
glibc/pthreads. (set_thread_area syscall). So you need the Linuxthreads
implementation of pthreads and not NTPL.

Okay, thanks for clearing that up, cinap. That's pretty impressive,
actually. Do you plan to put together some kind of package that we can
just drop in and run? It makes a lot more sense to find that
everything is run under Plan 9 :)
