Revision 2f3f413e91620d2314be59870f4bd67292f7d2de authored by Eelco Dolstra on 19 June 2012, 03:01:46 UTC, committed by Eelco Dolstra on 19 June 2012, 03:01:46 UTC
Systemd can start the Nix daemon on demand when the Nix daemon socket is first accessed. This is signalled through the LISTEN_FDS environment variable, so all we need to do is check for that and then use file descriptor 3 as the listen socket instead of creating one ourselves.
