It could but that is not supported by default (there is no sysv init script) atleast not in Fedora.

I guess yoo could, but what is your point? By default on (x)?inetd system service is supported. Sure you can hack around that and make it an init daemon but should we support that? If you hack it to run it as a sysv init daemon then i guess you could use su in the init script (that doesnt exist) and run git-daemon as a system service and as an unpriv user at the same time.

The point is that it is meant to run as an xinetd service domain.

Actually you could specify in /etc/xinetd.d/git that you want to run it as an different user but you will still needs xinetd running. Administrator just might to want to run inetd just for Git.

I rather support a something that makes sense (admin being allowed to tune policy to allow git user daemons to log to syslog in case desired), than support some hypothetical scenario where some admin decides to hack some sysv init script to get Git daemon to run as an init daemon instead of the supported xinetd service domain.
