I know, that you are not responding to me, but i have one note: The boot speed is often used as argument for the systemd. But no all users are interested on boot time, then there are reaction as this (and as my). IMO, there aren't a lot information about other aspects of systemd and then people (include me) don't know about them. Until will be boot time again and again used as argument, then here will be responses as these. To be precise, i often read about these things: monolitic, binary files and boot speed. I don't like first two and i am not interested in latest. regards -- Slavko http://slavino.sk
