V4.1: missing path option for frontail in "Other Apps" sidebar (/etc/systemd/system/frontail.service)

Hi,
in openhab v3.x in the file “/etc/openhab/services/runtime.cfg” there was
a configuration option for the path to Frontail in the “Other Apps” sidebar
(as described here, for example)

This seems to be no longer available in v4.1. I wonder where this has been moved to?

Ah, I’ve just found the new location:

/var/lib/openhab/config/org/openhab/core/ui/tiles.config

I an afraid it is not a correct location. I might be wrong but, this place is internal storage area which should not be updated by user.

You need to look at proper places which serve as valid sources of configurations. Can you try with i.e. /etc/openhab/services/core.ui.tiles.cfg and see if, and what new files appear in /var/lib/openhab/config?
