It depends on the git version on the server. The interesting code is in
upload-pack.c, which is spawned by git-daemon to serve a fetch or clone
request.

See commit b790e0f67 (upload-pack: send shallow info over stdin to
pack-objects, 2014-03-11), which lays out the history. Since that commit
(in git v2.0.0), there should be no tmpfile needed.

This shouldn't be happening with git v2.11. Are you sure that the "git
daemon" invocation is running that same version? I notice you set up a
restricted PATH. Is it possible that /usr/local/bin or /usr/bin has an
older version of git?
