w /proc/acpi/wakeup - - - - USBE
The tmpfiles method is recommended in this case since systemd doesn't actually support /etc/rc.local."
Does that means that I need to move all the content from /etc/rc.local to /etc/tmpfiles.d? For example this is my actual /etc/rc.local: ~ $ cat /etc/rc.local #!/bin/bash # # /etc/rc.local: Local multi-user startup script. #

If this is the case, how do you guys would convert the FOR loop!?
For ethtool, just create a separate service that executes that command. Everything else you do is writing to /sys, so you can have one giant tmpfiles.d file. For the for loop: w /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor - - - - powersave w /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor - - - - powersave w /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor - - - - powersave w /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor - - - - powersave Also, I don't think it's an error if the file doesn't exist, so you can just do cpu0..cpu16 or whatever if you feel like.
