Our gitolite package currently creates all (including gitolite-admin.git) git repositories with references to "/usr/bin/perl" as shebang, which makes it completely useless on serverside. Given that the server side in the case of a gitolite from Guix runs an environment where you will not run perl from /usr/bin/, you will have to change all hooks manually currently.
When you install perl into the profile of the user which hosts the repositories and change the shebangs, gitolite can be used.
