address@hidden Version Control
address@hidden Version Control
+
+The @code{(gnu services version-control)} module provides the following
services:
+
address@hidden {Scheme Procedure} git-service [git @var{git}] @
+ [base-path ``/var/git/repositories''] @
+ [port ``9418'']
+
+Return a service to run the @uref{https://git-scm.com, git} daemon version
control
+daemon.
+The git daemon runs as the @code{git} unprivileged user. It is started with
+the fixed parameters @code{--informative-errors} and @code{--syslog}. You can
+pass the parameter @var{base-path}, which remaps all the pathrequests as
+relative to the given path. If you run git daemon with
address@hidden /var/git/repositories} on example.com, then if you later try
+to pull @code{git://example.com/hello.git}, git daemon will interpret the path
+as /var/git/repositories/hello.git.
+Furthermore it takes the parameter @var{port} which defaults to 9418.
+Run @command{man git daemon} for information about the options.
