"[...]However, tmpfiles may also be used to write values into certain files
on boot. For example, if you use /etc/rc.local to disable wakeup from USB
devices with echo USBE > /proc/acpi/wakeup, you may use the following
tmpfile instead:


/etc/tmpfiles.d/disable-usb-wake.conf


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!?

I think that tempfiles can not execute commands, only create/write to
files. If you want to run some commands, you should probably create
some custom unit files.

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.

Slightly off-topic, but you should really read this:

I am fairly certain that tmpfiles.d understands "*", so you could
probably get away with one line for something like that.

It doesn't for the 'w' type. Globbing is specified explicitly where it's
supported. I don't know if that was an explicit design decision though. You
might have yourself an easy patch if you want to contribute.

It will be supported in next release:
