not to mention other issues like the systemd journal now writing everything from 
stdout and stderr of programs to it's logfile, with the associated flash wear 
this would cause.

Desktop distros are largely (but not entirely) moving to systemd, what embedded 
distro are you aware of that has moved?

Also, what Enterprise distro has moved? RHEL 7 is going to ship with systemd, 
but since it hasn't shipped yet, we don't know what it's acceptance is going to 
be in the enterprise space.
