Updating builtin or system packages

Currently Pkg will ignore built-in packages.

We need a way for Pkg to update built-in packages.

On Ubuntu and Debian, system packages are updated like so:

apt-get update
apt-get upgrade

On Slackware:

# slackpkg update
# slackpkg install-new
# slackpkg upgrade-all
# slackpkg clean-system

TODO

So, on Puppy we should have:

pkg upgrade      # update all system repos (download "doc" files, [convert if needed], install)
pkg update       # update installed packages, including built-ins

Currently Pkg will ignore built-in packages. We need a way for Pkg to update built-in packages.

Solution

• allow updating and "removing" builtins:
  • use custom code for removing package if it's a built-in
  • see the /usr/sbin/remove_builtin script:
    • rm all files listed in ~/.packages/builtin/<pkgname>
    • if it had a .desktop file, run fixmenus
    • show extra message saying "built-ins" need a remaster to be properly removed

Implementation

A pkg_uninstall_builtin() function, based on /usr/sbin/remove_builtin, called by pkg_uninstall():

If the package to remove is a built-in (can use is_builtin_pkg() to check), then use the new func to remove it.
