Of course this goes to a General Resolution

But you can trivially automate both the process of giving a list of the exact versions of each piece of software, and the process of building a filesystem that precisely corresponds to such a list.

Currently it's even worse because most distributions, due to their ancient packages and not including all software, force users to install some software on their own, sometimes in a way that isn't tracked by the package manager, which means you can't even produce the list at all.
