Git is nice, trust me. It take a little while to get used to, but it
is very neat.
Notice that the git migration is uclibc wide

If you can comprehend C++ then git shouldn't be a problem either :P

See my mail of last month:
If you put git repos in your ~/git/ dir and make sure you have a
git-daemon-export-ok in them, then they can be accessed through git://
and cgit just like the "official" repos.
See the git documentation (http://git-scm.com/documentation) for info
about creating (cloning) repos.

That's almost the situation today as well:
git shortlog -n -s --since='feb 12'
In other words, 92% of all commits since the last release has gone
This doesn't mean that it has to be doing all the work. If you could
help review patches and ack/nack, and then send me a pull request of
everything you think is good then that would be a big help.

I'm certainly open to discuss the details - Do you have any suggestion
how we could do this better?

Hard to do as this is done uclibc wise and has been pending for a long
time. There's imho no real problem with refining our work flow as we
go (we're entering release freeze this weekend anyway).

The fact that you can commit locally means that you can fix the
problem locally just as easily, it's just the path to the "official"
tree that takes a bit longer.

A seperate tree still means that you can easily test out changes
(yours or from someone else) before they get integrated into the

I partly agree. It's a combined people/technical problem.
