Suggested by Andreas Enge <andreas@enge.fr> at <http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00325.html>. * guix-package.in (latest-profile-number): Remove. (switch-symlinks): New procedure. (roll-back)[switch-link]: Use it. (guix-package)[process-actions]: Always choose NUMBER + 1 for the new profile. Use `switch-symlinks' instead of `symlink'. Remove code to delete PROFILE when it exists since `switch-symlinks' has the same effect. * tests/guix-package.sh: Adjust existing `--roll-back' tests. * doc/guix.texi (Invoking guix-package): Document this `--roll-back' behavior.
