Thanks, that's very interesting, and the differences are good to know. I played around with things like busybox a few years back, but have to admit that now that embedded systems like the RPi can run full Linux distros, I've obviously found those easier to develop for. In a message, hippo pointed me to the controversy surrounding systemd, it seems the only two distros that haven't adopted it as the default yet are Slackware and Gentoo. I guess I should start keeping an eye on those and other distros as well.
