[systemd-devel] systemd-coredump gets terminated during shutdown

[Joel Holdsworth]

Hi All,

I have an issue with the standard unit file: 
./units/systemd-coredump at .service.in

In my use case if the main application crashes twice in 2-minutes, the 
system will reboot into a recovery environment. I'm using 
systemd-coredump to capture the coredump files, but the problem is that 
if the reboot is triggered, then the coredump process is killed during 
shutdown before the coredump has been written to disk.

First of all, I'm having trouble correcting this behaviour. The 
systemd-coredump at .service should have no Conflicts=shutdown.target, and 
it must have Before=shutdown.target. I tried making similar changes to 
the corresponding .slice and .socket - but for some reason the coredump 
process is still getting killed. Is there any way to make systemd log 
the reason why a process was chosen for termination?

Also, the coredump process need to complete before the the relevant 
partition is unmounted. Is there a way to do that?

These are all systemd n00b questions. But the bigger question is about 
whether this is a bug in the standard unit files.

Thanks
