Thank you, @maDDin1338, for the explanation. Yes, I’ve dedicated a raspberry to run OH exclusively, so there’s normally only 1 container running. Just when upgrading to the next version, I start a new container, but after successful upgrade I delete the old one.
I was concerned about an older article (64 bit setup on RPi 4), where there seemed to be quite some reluctance to go for the 64 bit system on RPi 4… But since the next OH version will be 64 bit exclusively, I’ll have to switch latest in July…
Anyway, the referenced post is quite old (started 2020, last update 2022) and several new OH versions have been released since then. So is it meanwhile advisable and efficient to run OH on an RPi 4.0B with 4GB RAM with 64 bit in the one-and-only docker container? I assume yes, but would appreciate any feedback or warning…
