I was asked on IRC to test this with the Debian package (1:26.1+1-2).
It works:
After starting the emacs.socket unit, systemd opens the socket:
+---
| [...] /run/user/[...]/emacs [...] users:(("systemd",pid=2375,fd=23))
+---[ `ss -lxp | grep emacs` ]
Running `emacsclient` then starts `emacs` and the socket is passed to
emacs:
+---
| [...] /run/user/[...]/emacs [...]
users:(("emacs",pid=12153,fd=3),("systemd",pid=2375,fd=23))
+---[ `ss -lxp | grep emacs` ]
I've attached the .socket and .service units I'm using as someone was
asking for them (enable only emacs.socket to start emacs on demand); I
also have a wrapper script `e` which calls `emacsclient` with the
`--socket-name=${XDG_RUNTIME_DIR}/emacs` option (this would probably
also be safe to use by default if XDG_RUNTIME_DIR is set).
