I believe that the plan is to promote the pkg tool somewhat closer to = the base system. Upgrades will do the same sort of thing that they do = currently for ports: 1. First check if the version of pkg is the latest 2. If not, upgrade it 3. Do the real upgrade The package for package is simply a tarball. It may be advantageous to = separate the pkg and pkg-static binaries into different packages, so = that pkg can always install pkg-static and pkg-static can always update = pkg. There is no guarantee that the pkg tool from X.Y can install any = packages from X+n.Y.m other than the pkg-static binary, which can then = upgrade the rest of the system. The provision of pkg-static prevents us from being in the situation that = I encountered trying to upgrade a Debian system (and ending up with a = mess requiring a full reinstall) where apt needed a newer glibc and the = glibc package needed a newer apt to install it. We will always provide = a pkg-static for every supported branch that can be installed by any = earlier version of pkg (because it=E2=80=99s just extracting a = single-file archive - and in the absolute worst case you can do this by = hand) and can install newer packages.
