Hey @markusl - just to make sure... Is this failing for you?
In principle, this message should only be a warning...

I still think this is a bug (putting the timestamp file in a possibly read-only location isn't so great), but if that is just a warning, the urgency of fixing this is a little lower 😅

@RomainMuller now that you asked, it seems to be a warning only, but I was a little bit confused as it looked like an error to me :)
