However after actually trying this approach I have found out that when post_fetch_checkout runs at initial "clone", HEAD points at refs/heads/master, but refs/heads/master does not exist! So just checking HEAD is not enough, I need to verify that it points to something valid. How about this: From: Marcin Owsiany <marcin@xxxxxxxxxx> Date: Sun, 24 Jun 2012 22:40:05 +0100 Subject: [PATCH] git-svn: don't create master if another head exists git-svn insists on creating the "master" head (unless it exists) on every "fetch". While it is useful that it gets created initially (users expect this git convention), some users find it annoying that it gets recreated, especially when they would like the git branch names to follow SVN repository branch names. More background in http://thread.gmane.org/gmane.comp.version-control.git/115030 Make git-svn skip the "master" creation if HEAD points at a valid head. This means "master" does get created on initial "clone" but does not get recreated once a user deletes it.
