Re: [systemd-devel] Calling shutdown while executing a service
Hello,
/usr/local/sbin/local is a bash script which calls several functions.
When
one of these functions fails, i.e. returns another value than zero, the
script calls this function:
die() {
STRING=$1
echo 2 Error occured in function ${STRING}
echo Press any key to reboot (sorry for your inconvenience)
read -n 1
shutdown -r now
}
Now I have the case that one of the functions fails. But after pressing
a
key, the computer does not reboot immediately, but schedules the reboot
for approximately two minutes in the future and then continues to
execute
functions, till the two minutes are over.
Most likely systemd is waiting for your service (or some other
service) to finish before it proceeds with shutting down.
Consider issuing systemd-analyze set-log-level debug before you try
this. This turns on debug output which might tell you what precisely
systemd is waiting for.
I added that line at the beginning of die(), but that did not result in
additional screen messages. But I am sure that the delayed shutdown
happens because systemd is waiting for my service to finish. Is there
another way to prevent that, than adding an exit command at the end of
die()?

What do I have to change to let the computer reboot immediately after the
keystroke?
