that's not enough! Linux is GPL'ed, that means that _all_ software which
uses source-code-pieces from it or is linked against (parts of) it has to
be under GPL too. (If you want to survive: don't discuss this with RMS -
he looks much closer on GPL-paragraphs than any other :-) )

Just try to ask that for permission to write some Linux-extensions.
Another filesystem and another executable-format (eg. an extended ELF
would be nice). An easier to handle LILO or ..............
This way it would (IMHO) have two advantages: you can profit from a
running system which is very stable and proved. Your writings would get
back to community and would (perhaps) get used.
