  6. # summary of how this script can be called:
  7. #        * <postinst> `configure' <most-recently-configured-version>
  8. #        * <old-postinst> `abort-upgrade' <new version>
  9. #        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
  10. #          <new-version>
  11. #        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
  12. #          <failed-install-package> <version> `removing'
  13. #          <conflicting-package> <version>
  14. # for details, see /usr/share/doc/packaging-manual/
  15. #
  16. # quoting from the policy:
  17. #     Any necessary prompting should almost always be confined to the
  18. #     post-installation script, and should be protected with a conditional
  19. #     so that unnecessary prompting doesn't happen if a package's
  20. #     installation fails and the `postinst' is called with `abort-upgrade',
  21. #     `abort-remove' or `abort-deconfigure'.
