I am note entirely sure if this feature has merit or not, but I don't want to comment on that. However, I'd like to suggest that if you do this, please consider replacing this line: <snip> ExecStart=/bin/bash -euo pipefail -c 'mkdir -p /run/sysctl.d && chcon --reference=/etc/sysctl.d /run/sysctl.d && echo "kernel.printk = 4" > /run/sysctl.d/01-coreos-printk.conf' </snip> by something like this: <snip> ExecStart=/usr/bin/systemd-tmpfiles --create - StandardInputText=f /run/sysctl.d/01-coreos-printk.conf - - - - kernel.printk 4 </snip> Benefits: no shell, single process forked, no explicit selinux stuff, or explicit mkdir, and other MACs will be honoured too if they exist.
