Extra configuration to append to the default ~/.gitolite.rc.
This should be Perl code that modifies the %RC configuration variable. The default ~/.gitolite.rc content is generated by invoking gitolite print-default-rc, and extra configuration from this option is appended to it. The result is placed to Nix store, and the ~/.gitolite.rc file becomes a symlink to it.
If you already have a customized (or otherwise changed) ~/.gitolite.rc file, NixOS will refuse to replace it with a symlink, and the gitolite-init initialization service will fail. In this situation, in order to use this option, you will need to take any customizations you may have in ~/.gitolite.rc, convert them to appropriate Perl statements, add them to this option, and remove the file.
See also the enableGitAnnex option.
