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.
