Description

Subsystem Server

Systemd can create sockets (TCP, unix domain and more) for services, see https://www.freedesktop.org/software/systemd/man/systemd.socket.html Could this be supported? The socket doesn't disappear when the service is restarted (connections get queued) and it also helps with dependencies between services.

Research direction
Study Ktor's server architecture, specifically how sockets are created and managed (e.g., in modules like ktor server cio or ktor server netty). Research systemd socket activation protocol and how to obtain file descriptors from the environment. Look for any existing discussions or linked issues in the repository. Propose a minimal design that integrates systemd socket activation without breaking existing functionality.
