who is spawning the job? isn't it pid-1? If you say no, then it means you don't know how the activation works (look at /usr/share/dbus-1/systemd-service/org.freedesktop.hostname1.service). If you say yes, but the actual job is running as another pid, then what is the point of pid-1 brokering? isn't dbus suppose to spawn the child instead of pid-1? The problem here is, you never know what kind of data you will receive in pid-1 through dbus requests before forking the child. This is what I say exposing pid-1. If someone exploit here (before spawning the child), it will lead them to other pid-1 resources. Thats why people are saying init should not be doing all these work. demons are there to do these work. even if daemons get compromised, they will not provide other important resources. Don't say SElinux is integrated with systemd so there is no way to exploit systemd. SElinux will not help in this situation. > You can call the people who are actually building things and writing > code moron.

[1] [1] all are stupid arguments assuming that whoever ask question against systemd are not appreciating its features, they don't know about it's design and they are trolls from reddit.com/r/[a-zA-Z0-9]*/*. Your post which started arguments between you and me says "people bashing systemd have very little technical information", do you still think people arguing against systemd don't know how it works?
