Some of this is pulled directly from the git-svn man page.

Push a local git-branch to a new remote new-svn-branch

git svn branch new-svn-branch

now there is a new remote tracking branch, confirm with git branch -r to push local git-branch changes to the new svn branch git checkout git-branch git rebase --onto new-svn-branch OR from master (this seems to work better) git rebase --onto new-svn-branch master git-branch

I think I found a typo in your guide and I wanted to draw your attention to it.

In the section Data > Add users and domains > Adding template, one of your SQL lines looks like the following:

INSERT INTO users (id,name,maildir,clear) VALUES
	('email@address','short description','foldername/',encrypt('password') );

I think that instead of 'clear' as the last field being inserted into, you meant 'crypt' because you are encrypting a password.
