Here one can host one's own free software packages for Ubuntu. http://en.wikipedia.org/wiki/Personal_Package_Archive http://blog.launchpad.net/ppa/personal-package-archives-for-everyone https://launchpad.net/ubuntu/+ppas Then the package works via apt and the software centre, so for example can get updates. It can be automated up to a point. I am scripting bits of it. There will be potential hiccups -- 1) I gpg sign the packages. I enter my password for this. Even this can be automated with expect or perhaps directly with the debuild (debian package building) tools, and if sagemath took over the PPA and the key and signing, many people can be in a team and sign a package, I think. You sign to upload, launchpad rebuilds and signs the packages with the PPA key. 2) If upstream changes become incompatible with the current rollout, the PPA will suddenly break many poeple's sage. I do (some very basic) testing of the package before I upload. Even this can be automated, I guess. How do I re-run all the tests in a binary installation? sage -testall?
