- change tmpfiles rule user/group to default daemon user/group set by
gitDaemon module - git:git
- add chown of created repo to user/group of daemon after local subtest
on server (that run from root user) pass. Without it next subtest doing
clone from remote fails with "detected dubious ownership in repository"
on server side.
git-daemon won't start up if its project directory (here /git) doesn't
exist. If we try to create it using the test harness, then we're racing
whether we manage to connect to the backdoor vs. the startup speed of
git-daemon.
Instead, use systemd-tmpfiles, which is guaranteed(?) to run before
network.target and thus before git-daemon.service starts.
This test is sometimes flaky on hydra as at the time of the `git clone`
the network isn't really configured yet[1]. That problem doesn't seem to
occur locally but if you run it on a machine with high enough load (such
as hydra build machines). Hopefully this will make the test not flaky
anymore.
