openhab tries to access directories in /var

[tobei-0049]

dear all,
I'm migrating from openhabian to the snap based version running on fedora 34 using snap version 3.1.0
openhab works stable, but I always try to configure the software so that no errors or warings appear in the logs...

to avoid following warnings it would be possible to bind-mount the directories, but I guess a better way would be introducing ENV-variables to the corresponding locations.

regards
Thomas
