systemd, many: no reload when enabling or disabling services
Daemon reload is a very expensive operation, that comprises of systemd dumping
all of its state and performing a cold start, by reloading everything from disk
and rerunning all generators. On a slow device it can easily take significant
time, rendering the system barely usable.
While installing snaps or adding snap services, snapd would perform multiple
implicit reloads by calling systemctl enable/disable without --no-reload flag.
