You probably mean daemon-reexec, which also does not restart services (it better not, would be really problematic if it did).
I do mean reload, which has uses, otherwise it wouldn’t even exist and services would simply always reload: You may not want to reload yet, but keep a working state of service definitions in systemd while editing things, similar to typing away in a code file in production without saving yet.
I don’t see why I would need to “save” all my service definitions to get a usable (non-spammy) mount back, especially when my mount isn’t even part of systemd. How does the message even get sent by mount when mount is not aware of systemd?
PS: systemd can replace my text editor over my cold dead body
Yes, that’s an organ, but you’re thinking of a portable binder of preprinted tables designed for personal management.
