Running HA with read-only root FS

Configuration
1

I am trying to run HA with a read-only root file-system. I have moved the config dir to a R/W partition. HA seems to be working ok, however are there any other folders of DB that HA needs to have R/W access to? E.g for persistence to work?

Thanks for your help.

AFAIK persistence is done in the SQLite database file home-assistant.db. If you’re using Z-Wave then you’ll get 2 more files zscene.xml and zwcfg_XXX.xml. I don’t know of any others.

Any data that Home Assistant stores is in the config directory. Z-Wave, history DB, package requirements for platforms etc.
