Hello. I'm trying to understand how deb package update happens in details.Is it transaction of some kind? Atomic? Temp dirs and move? And so on. I cant find any info about this in official docs and in Google in general.
I want to package our in house php code in deb and deploy it in production servers. But nature of this code implies what there is shouldn't be any race of mix of old\new files.
