pistachio with busybox/shell & build system

Hi l4 hackers,

I'm new here but I've been following this l4 list irregularly before.  
Fine that development still goes forward.

Can anybody give some hints/tips what would be necessary to run  
busybox or some kind of shell with l4-pistachio kernel? Is that  
possible anyway? What kind of
changes will glibc require? I guess changes regarding syscalls are at least
needed.

Does it make a sense to change l4-pistachio's build system to look  
like linux's?
I'm working on it but still not sure about it. I've adopted linux's  
lxdialog and
wrote appropriate makefiles. Works fine for me so far.

Regards,
Ladislav.
