• You have: Apache httpd, gitweb, git repos in users’ homes ~user/git/*
• You want: serve these repos under *http://gitweb.example.org/~user/…*

By default, gitweb only supports serving repos from one project root. For DragonFly we wanted not only to serve the main project repo in gitweb, but also serve the personal repos of developers. These repos are located in the users’ home directory in ~user/git. Turns out I could make this work without having to modify the gitweb source. By adding the following fragment to gitweb’s config file /etc/gitweb.conf, we can now serve the users’ personal repos:
