Yes. Indeed the emacs package (on my Arch install) installs both /usr/bin/emacs and /usr/bin/emacs-27.1 so it could keep the old version of the binary around, and also the lisp in /usr/share/emacs/27.1/. But then the question is when and how are those files eventually going to be removed? And what about the files in /usr/share/emacs/site-lisp/? If they were byte-compiled with the newer version, is there a guarantee they'll work in all the older versions? > Do distros forcibly remove those versioned files and directories when > they install a new version? Yes, as said. Usually the package manager has some database of package- and the files it installed and will remove the files when the package version is removed in order to clean up. >> And from a distro packager's point of view, the additional >> user-convenience of enabling users to compare emacs version X against >> the current version surely doesn't justify the added maintenance >> costs. > > In the case of Emacs, I see no additional costs if all they do is > refrain from removing the files belonging to the previous versions. > The costs are of the end-user. They'd probably still receive bug reports for the old version. Bye, Tassilo
