Now, I'm thinking to move uml_utilities to a CVS repository, either the

And give to many write-access to it (for public read access we'll see, there
are security problems with pserver. Having a rsyncable CVS repos like for the
kernel should be ok - the repo

Correct. I think uml_net would need to manage a database of who opened what
to do what you suggest.
I also looked at the versioning for uml_net

Ok...
There are too much little things to fix to have a central maintainer, IMHO.
And nobody volunteered, sadly, and I can't either.
Is there really that much to fix? T
sure, allow me to check if everything looks fine (at least) to me...

See my homepage (at the end of the signature). Use -V7 for now..., it's a good
release (or -V8-rc2 with the fixup if you need 2.6.11 host kernel, but it's
still a bit experimental).

This implements a hardware random number generator for UML which attaches
itself to the host's /dev/random.
