git-daemon

# conf.d file for git-daemon
#
# Please check man 1 git-daemon for more information about the options
# git-daemon accepts. You MUST edit this to include your repositories you wish
# to serve.
#
# Some of the meaningful options are:
#   --syslog      --- Enables syslog logging
#   --verbose     --- Enables verbose logging
#   --export-all  --- Exports all repositories
#   --port=XXXX   --- Starts in port XXXX instead of 9418
#
GITDAEMON_OPTS="--syslog --base-path=/var/git"

# To run an anonymous git safely, the following user should be able to only
# read your Git repositories. It should not be able to write to anywhere on
# your system, esp. not the repositories.

git-daemon@.service

[Unit]
Description=Git Repositories Server Daemon
Documentation=man:git-daemon(1)

[Service]
User=nobody
Group=nobody
EnvironmentFile=/etc/conf.d/git-daemon
# Ignore non-zero exit status, access error makes git-daemon return them
ExecStart=-/usr/libexec/git-core/git-daemon --inetd --base-path=/var/git --verbose $GITDAEMON_OPTS
StandardInput=socket
StandardOutput=inherit
StandardError=journal

HOWTO;

Edit git-daemon@.service to your local configuration. particularly this line;
"ExecStart=-/usr/lib/git-core/git-daemon --inetd --base-path=/home/jeremiah/GENIVI/local-repos --verbose $GITDAEMON_OPTS"
Obviously on our git.projects.g.o server the base path is /srv/repositores/ and I've changed where you find the git-daemon to match Debian.

1. Move the git-daemon@.service template and git-daemon.socket files into /lib/systemd/system/
2. sudo systemctl enable /lib/systemd/system/git-daemon.socket
3. sudo systemctl start git-daemon.socket

That should work.
