Delay service start after multi-user.target

Allows code server service to start after system reboot without fail: "Failed to determine user credentials: No such file or directory"

Problem

My rather clean installation of YunoHost 11.0.11 (and previous stable one) failed to start code-server.service each time the machine was rebooted.

code-server.service journalctl:

-- Boot 03734629852c4297829135e8f364cbda --
Jan 05 17:11:16 systemd[1]: Started VS Code Server.
Jan 05 17:11:16 systemd[798]: code-server.service: Failed to determine user credentials: No such file or directory
Jan 05 17:11:16 systemd[798]: code-server.service: Failed at step USER spawning /opt/yunohost/code-server/bin/code-server: No such file or directory
Jan 05 17:11:16 systemd[1]: code-server.service: Main process exited, code=exited, status=217/USER
Jan 05 17:11:16 systemd[1]: code-server.service: Failed with result 'exit-code'.

Manual service (re)start worked.

Solution

Turns out it just need to start some of other services first. Everything needed is most probably reachable after "multi-user.target" requirement is satisfied. Solution was inspired by this article on shellhacks.com
