[Problem]: Startup script is trying to remove busy files

[UncleSamSwiss]

Description

I'm using ioBroker in BalenaOS (a docker based fleet management). With version 8.0.1 everything was working fine. When I tried to update to v8.1.0 (with balena, you simply update your Dockerfile and deploy the application), the error message below happens and the container exits. This happens in an infinite loop, of course.

My suggestion is: don't fail if rm can't delete something in /tmp. There might be files that are used by other applications or services running in the container (or as in my case are mounted into /tmp, see below).

mount | grep /tmp
tmpfs on /tmp/balena type tmpfs (rw,nosuid,nodev,mode=755)
tmpfs on /tmp/resin type tmpfs (rw,nosuid,nodev,mode=755)

Image version

v8.1.0

Hi Sam,
I get your point and will treat this as feature request, not as a problem (with possible hotfix) for the following reasons:

1. It is absolutely not supported and no good choice to run other services than the ioBroker itself within the ioBroker Docker container. So no other service should write data to /tmp
2. I don't mind a possible reason to mount a host folder to /tmp. 😄

The startup script tries to rm -rf /tmp/* because of keeping the container clean after updating or installing additional packages at the first run of the container. Maybe I can adjust this.

Regards,
André

Please test with v9.0.0-beta.2.

Stable Release of v9 is available. As I got no feedback to this I assume this is fixed. So I'll close this.
