1.19.1 no longer works: user promtail is currently used by process 546

I'll will check on Monday. I assume I's because the users home is tried to changed by the Ansible user module with a process running as the user and this fails.

It it is the case, I could add a check if the users current home will be changed and stop the promtail process before running this task. But this would add some complexity to the role only to change the users home.

@shinebayar-g
Thanks for reporting - I was not expecting that change to create issues. I've created a test case for catching regressions in the future #141

@hafu
I'd gladly appreciate if you provide a fix for the regression - thank you :-)

I could reproduce the issue. And came up with two options:

1. As mentioned by @shinebayar-g #138 (comment) omitting the home. This would not touch the home of the user on existing installations (/) and on new installations it would be the default /home/promtail or /home/{{ promtail_system_user }}.
2. Check for the user and if exists make sure there is no process running by stopping promtail when the home changes. I've added some additional tasks: a481b4d

What do you think?

Thanks for reaching out - personally I believe number 1) is the less intrusive one and with the less maintenance overhead in the long run.
