Which init was used in your experiments? If it was systemd or anything else honoring tmpfiles.d, /lib/tmpfiles.d/systemd.conf has: F! /run/utmp 0664 root utmp - > Thus I am asking your advice, whether it is safe to not create > /var/run/utmp in initscripts. Depending on the init, removing initscripts is already allowed, and it's likely that fresh installs do not even get it installed anymore. Chris
