hordes of suckers (loyal developers), you have been tricked (chosen) to

The maintainer's git time is spent on three activities.
the "master" branch, and how "rebase" works. Also discussed
is how this applies to individual developers who sends patches
upstream.

Exactly my feeling. I was sort of waiting for Catalin to speak
up. With its basing philosophical ancestry on quilt, this is
the #1' commit.

So exactly *because* the SHA1 hash is cryptographically secure, the hash
itself doesn't actually tell you anything, in order to fix a corrupt

non-corrupt version.

This is the right thing to do, although it's usually best to save it under
it's full SHA1 name (you just dropped the "4b" from the result ;).
Let's see what that tells us:

Ok, I removed the "dangling commit" messages, because they are just
messages about the fact that you probably have rebased etc, so they're not
after the offending branch is fixed.

This uses two files, $GIT_DIR/info/allowed-users and
allowed-groups, to describe which heads can be pushed into by
whom. The format of each file would look like this:
- refs/heads/master junio
- +refs/heads/pu junio
- refs/heads/cogito$ pasky
- refs/heads/bw/.* linus
- refs/heads/tmp/.* .*
- refs/tags/v[0-9].* junio
+ refs/heads/master junio
+ +refs/heads/pu junio
+ refs/heads/cogito$ pasky
+ refs/heads/bw/.* linus
+ refs/heads/tmp/.* .*
+ refs/tags/v[0-9].* junio
With this, Linus can push or create "bw/penguin" or "bw/zebra"
or "bw/panda" branches, Pasky can do only "cogito", and JC can
do master and pu branches and make versioned tags. And anybody
can do tmp/blah branches. The '+' sign at the pu record means
that JC can make non-fast-forward pushes on it.

Git can be run in inetd mode and in stand alone mode. But all you want is
let a coworker pull from you, and therefore need to set up a git server
