What's the Git approach to publish a patch queue?

Question

I am used to Mercurial mq extension to maintain a set of custom patches over the upstream. They can be published as a separate repository aside from the upstream. Now in git

Answer 1

Considering the comments given, it seems an approach more or less equivalent to Mercurial's mq would be using guilt. Unlike mq, guilt does not directly provide an interface for a "patch repository", but you could turn the .git/patches/ into a .git repository manually.
