  10. #        * <old-postinst> `abort-upgrade' <new version>
  11. #        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
  12. #          <new-version>
  13. #        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
  14. #          <failed-install-package> <version> `removing'
  15. #          <conflicting-package> <version>
  16. # for details, see http://www.debian.org/doc/debian-policy/ or
  17. # the debian-policy package
  18. #
  19. # quoting from the policy:
  20. #     Any necessary prompting should almost always be confined to the
  21. #     post-installation script, and should be protected with a conditional
  22. #     so that unnecessary prompting doesn't happen if a package's
  23. #     installation fails and the `postinst' is called with `abort-upgrade',
  24. #     `abort-remove' or `abort-deconfigure'.
