Sorry, totally missed your comment before. Thanks, it will be useful then for a lot of issues, but for the next project.
Also, it seems openhab is now snap official, but not one year ago I think when I’ve found issues with usb Openhab 3.0 - no access to z-wave usb-stick good news that it is actually better supported. I ended using docker as a workaround, because I think that appliances would be a better option, but I had to install deconz, mosquito, and 3th party not trusted software that I decided to use docker.
But I will try lxd in the future, I never find out that option in “internet forums”.
Thank you @ogra
