I guess I would fit mostly but I have no idea of the kernel internal
stuff. Also I'm a bit short on time.

exactly this point. Maybe somebody like Mike Gair.

I'm glad you are still interested. I'm always happy when I see mails
from you at the DECnet for Linux list.

There are still some people interested in it. Btw. on Debian popcon
counts 5356 users.
