How much do you know about git? Short version: git checkout git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git e2fsprogs cd e2fsprogs git branch pu origin/pu git checkout pu To update to a newer pu once you have done the above steps cd /path/to/checked-out-e2fsprogs-repository git fetch git checkout pu git reset --hard origin/pu (Note that the "git reset --hard" will blow away any local commits you might have made; this isn't a substitute for a full-blown git tutorial. The reason for the git reset is because the pu branch is constantly getting rebased.) A good place to start for explaining the concepts of git (and why git is so great) is here: http://utsl.gen.nz/talks/git-svn/intro.html The bits about "git svn" won't apply for e2fsprogs, but the concepts of git are really well explained in the above web page. For the "crash course", this is pretty good: http://git.or.cz/course/svn.html Other good starting points for git are: http://www.kernel.org/pub/software/scm/git/docs/gittutorial.html http://www.kernel.org/pub/software/scm/git/docs/everyday.html - Ted
