I am not sure and I have used systemd through NixOS in particular for a good half a decade now. While I have not tried to fight it, it does come across as being somewhat opaque to me, but I can generally deal with it and have not gone out of my way to “read a book” on it. It did annoy the hell out of me about a month ago when I had this “conversation” with it: > sudo reboot [sudo] password for ninjin: Failed to reboot system via logind: Connection timed out > sudo halt Failed to set wall message, ignoring: Connection timed out Failed to reboot system via logind: Connection timed out Never expected to be in a situation where I could not shut down a machine cleanly like that. But maybe I was missing something?
