[PATCH] gnu: services: Add git-service.
Right now, this service does not work (vm does not build) when I try to build the vm
with "./pre-inst-env guix system vm ../testvm-git.scm", where ../testvm-git is a file I will append in the 2nd follow-up message.

+@subsubsection Version Control
+
+The @code{(gnu services version-control)} module provides the following services:
+
+@deffn {Scheme Procedure} git-service [#:git @var{git}] @
+ [#:base-directory "/var/git/repositories"] @
+ [#:user-directory? #f ""] [#:port 9418] @

+
+Return a service to run the @uref{https://git-scm.com, Git} daemon, a really simple
+TCP Git service which exposes local repositories for anonymous remote access.
+
+The git daemon runs as the @code{git} unprivileged user. It is started with
+the fixed parameters @code{--syslog}, @code{--reuseaddr} and
+@code{"--no-informative-errors"}.
+You can pass the parameter @var{base-directory}, which remaps all the directory
+requests as relative to the given directory. If you run git-service with
+@var{base-directory "/var/git/repositories"} on example.com, then if you later try
+to pull @code{git://example.com/hello.git}, git-service will interpret the directory
+as @code{/var/git/repositories/hello.git}.
+@var{max-connections} sets the maximum number of concurrent clients, it defaults to 32.
+Set it to 0 for no limit.
+@var{user-directory} allows allows ~user notation to be used in requests. When
+specified with no parameter, requests to @code{git://host/~alice/foo} is taken as a
+request to access @code{foo} repository in the home directory of user @code{alice}.
+If @var{user-directory "path"} is specified, the same request is taken as a request
+to access @code{path/foo} repository in the home directory of user @code{alice}.
+The parameter @var{directory "foo"} adds the directory "foo" and its subdirectories
+to the whitelist of allowed directories.
+Furthermore git-service takes the parameter @var{port}, which defaults to 9418.
+Run @command{man git daemon} for information about the options.

Hi, I make and send a new patch based on yours, which rename
'git-service' to 'git-daemon-service', and put most documentation to the
'git-daemon-configuration' part.
I tested it with the default configuration and 'user-path', it works
fine! I'd like it to deprecated yours, what do you think?
Thanks!
