Hi systemd devs and users,
I want to implement custom power off method.
I added to the yocto script: /usr/sbin/halt.local which will power off
my machine.
But from what I see it is not correct.
Ive got this from my machine:
[ OK ] Reached target Shutdown.
Starting /usr/sbin/halt.local Compatibility...
My power off
[ 76.916101] EXT4-fs (mmcblk1p1): re-mounted. Opts: (null)
[ OK ] Started /usr/sbin/halt.local Compatibility.
[ OK ] Reached target Final Step.
Starting Power-Off...

[ 77.409285] systemd-shutdown[1]: Powering off.
[ 77.431515] reboot: System halted
"My power off" will power off machine, but to early.
I want to call my script after:
"[ 77.409285] systemd-shutdown[1]: Powering off."
How to do it?
Best Regards
