First: I know it’s mostly a spare time thing here and I’m grateful for each and everyone contributing their time and effort here.
With that out of the way: I beg to differ here! I did my openHABian “upgrade system” exactly 23minutes after Kai updated the sources. As you pointed out, users of openHABian should use the built in upgrade and not only “apt-get update && apt-get upgrade” - and I wanted to update the pi firmware, which fixed some security issues. If I did it in the shell, I certainly would have noticed that openHAB is about to upgrade also…
So, a short: “hello everyone, I’m about to update tonight!” in the usual announcement post is sufficient in my eyes. Kai posted the announcement after updating the sources, what’s different, if he could just posted the announcement a few hours beforehand to just achieve awareness, that something is about to happen. As with every announcement, all users should get an email from the board, so they’re informed.
but perhaps it could also be turned around to a feature in openHABian: as Rich pointed out openHABian could “lock” to a specific version or could inform the user beforehand, that not only the “normal” apt-get upgrade is going on, but a major/minor release is about to happen?
