A brilliant idea. This allows us to transition smoothly to a more distribution friendly setup. I'm interested to see a list of spkgs which modify files (and offcourse the files being edited). Is SPKG_LOCAL really an environment variable used in sage? If so the next step might be to temporarily change it to SPKG_LOCAL/ packagename.versionnr before each install of an SPKG and see what breakes (probably a lot). But if we get things working again then uninstall is just as easy as deleting a directory. This would make the step to something like nix very small. Note that a lot of SPKG's also install stuff into something like python*/site-packages. And I second the idea that the list of files should not be autogenerated during install but be a part of the SPKG. Although the initial file lists in the SPKG can be autogenerated offcourse :). > If the file was just added, we'll keep track of it. And when the > package is uninstalled, it will simply be removed.
