core: HA InfluxDB integration fails with Read-only file system error following upgrade to Docker 25.0.x

The problem

Following an upgrade from docker-ce 24.0.7 to 25.0.1 the InfluxDB integration fails with the error message,

ERROR (influxdb) [homeassistant.components.influxdb] Cannot connect to InfluxDB due to '[Errno 30] Read-only file system'. Please check that the provided connection details (host, port, etc.) are correct and that your InfluxDB server is running and accessible.

No data is received in InfluxDB from HA after the upgrade from docker-ce 24.0.7 to 25.0.1.

The ‘[Errno 30] Read-only file system’ error message appears to be coming from a influx.write_api call in this code block of the InfluxDB integration.

The error may be caused by a change in mounting behavior introduced in moby v25.0.x that prevents multiprocessing from creating a /dev/shm file, as reported in this moby/issues/47158 issue. The influxdb python client uses multiprocessing.

If the issue is python multiprocessing and docker-ce 25.0.x related, other HA integrations that use multiprocessing may be impacted

Downgrading from docker-ce 25.0.1 to 24.0.7 restores the HA InfluxDB integration functionality, suggesting it is an issue brought about by a change introduced in docker-ce 25.0.x.
