Debian.

Userspace won't need any modifications to work, but I am slowly working
through the patches needed to get everything in the kernel converted.
And my patches for the networking stack weren't quite ready for the
merge window.

Ultimately to be included in distro kernels and really be useful I need
to make everything in the kernel that plays with uids and gids user
namespace aware so that is my goal for the next merge window. We will
see how that goes.

As for patches to userspace, all I think I will need is a small change
to useradd, and perhaps a helper function to validate the mapping into
the initial user namespace's uids. Aka is user A allowed to use uids
100,000-110,000?

I have a branch in my user-namespace.git with all of the rest of my
kernel changes if you want to play. Beyond that I expect most of the
user space changes (useradd etc) to land in ubuntu fairly shortly
after they are viable as I am working closely with a couple folks
at ubunut.
