The Debian Snapshot Archive http://snapshot.debian.org/ plays a crucial role in research reproducibility and repeatability. Does any other free operating system have the same concept of providing a snapshot archive?

Dana, Dana, Dana, Dana and 4 others shared this.
I'm not familiar with any other that has this.
Old packages archives, yes, but this is more than that =)
I've been told that Fedora also providers the full history of their packages but not repo data; and Ubuntu has some of the history, but they discard packages after a certain time.
