Systemd launchd comparison

May 26, 2020 · This framework makes it possible to construct multiple instances of running processes, isolate their resources (by avoiding conflicting resource configuration properties), and manage running process with a variety of process management solutions, such as sysvinit scripts, BSD rc scripts, systemd, launchd and supervisord. systemd is the first daemon to start during booting and the last daemon to terminate during shutdown. The systemd daemon serves as the root of the user space's process tree; the first process (pid 1) has a special role on Unix systems, as it receives a SIGCHLD signal when a daemon process (which has detached from its parent) terminates ...

Because D-Bus is intended for potentially high-resolution same-machine IPC, not primarily for Internet IPC, this is an interesting optimization. Systemd and launchd can both change the user IDs and group IDs of the process that it invokes. Because only changing UIDs are universally supported amongst process managers, I did not add a configuration property that allows you to change GIDs in a process manager-agnostic way. I'm looking for a comparison between the architectures of systemd and launchd.
