Hey, it's almost exactly what sd_notify() does. Instead of one character, it writes "READY=1" to a socket. Nothing more, no D-Bus, no additional libraries needed. In basic form it few lines of C code. Of course https://github.com/systemd/systemd/blob/0e4061c4d5de6b41326740ee8f8f13c168eea28d/src/libsystemd-daemon/sd-daemon.c#L414 looks much worse, but it packs more functionality than simply readiness signalling. -- Tomasz Torcz RIP is irrevelant.
