4 years ago Btw. the runlevel process is not essentially different whether I make sudo shutdown -h now (as user xbian) (see above) or make shutdown -P now (as user root and power off instead of halt, like Kodi does). The latter gives:
...
run-level 2 2020-04-27 09:23
run-level 2 2020-04-27 09:23
run-level 2 2020-04-27 09:23
Broadcast message from root@xbian
(/dev/pts/3) at 9:24 ...
The system is going down for power off NOW!
run-level 0 2020-04-27 09:24 last=2
run-level 0 2020-04-27 09:24 last=2
run-level 0 2020-04-27 09:24 last=2
...While shutdown from Kodi, there's terminal "unknown" in the broadcast message, see above. Now I'll try the hints from http://forum.xbian.org/thread-4085-post-36579.html#pid36579
I've already written this in the forum, but sadly no support there. After some own research I consider this a bug. Please correct me and explain, if I'm wrong.
I realized that there seem different shutdown routines whether I choose "shutdown" from the Kodi menu or do a
sudo shutdown -h nowfrom ssh. Shutdown scripts inside /etc/rc0.d/K... (symlinked to /etc/init.d/ by executing update-rc.d ...) get perfectly executed by a shutdown viasudo shutdown -h now, but not, when selected "Shutdown" from the Kodi menu. Also the messages showing below the progress bar are different between these two shutdown processes.Using
while true; do who -r;doneshow that the runlevels the system goes through are the same between these two ways of triggering a shutdown. One salience: Onsudo shutdown -h nowthe output is:while after using the Kodi menu it is:
So, there's no direct transition between runlevels 2 and 0. And in runlevel 0, there's no "last runlevel" entry. That might prevent some shutdown scripts from running, since as far as I understood upstart prevents some script executions depending on the previous runlevel. I think, that mechanism is coded in /etc/init.d/rc. So, one question nis: why is the shutdown process out of kodi going into some undefined runlevel between 2 and 0?
Xbian 1.0 is running on Base of Debian 10. On my system the readings are:
Debian 10 is normally running with systemd as startup system. https://wiki.debian.org/Init But Xbian is using upstart:
Is that intentionally?
Next question: How come that, although using Upstart, the scripts in /lib/systemd/system-shutdown/ get executed anyway? Both when using
sudo shutdown -h nowor Kodi menu shutdown.So, I consider a bug that there is no consistent way for having a script perform on startup and shutdown, either by
sudo shutdown -h nowor Kodi menu shutdown: The startup scripts in /etc/rc?.d/ work well, but the shutdown ones don't work via Kodi menu. The shutdown scripts inside /lib/systemd/system-shutdown/ work both ways, but that mechanism there doesn't provide a startup folder, does it?
