Taking this over.
+ 18 May 2013; Fabio Erculiani <lxnay@gentoo.org> git-1.8.2.1.ebuild, + git-9999.ebuild, +files/git-daemon.socket, +files/git-daemon_at.service: + add systemd unit supporting socket activation to 1.8.21 and 9999, fix bug + #468846 +
I could also create, test and attach here the unit that starts git daemon as a standalone daemon (not socket-activated), if somebody interested.
File a separate bug if you really want it.
