Bug#174200: apt: negative priorities in /etc/apt/preferences do not work as expected

[Denis Barbier <barbier@debian.org>]

Package: apt
Version: 0.5.4
Severity: normal

Hello,

I do not want to install libc6-2.3.1-6, so I tried to put in
/etc/apt/preferences:
  Package: libc6
  Pin: version 2.3.1-6
  Pin-Priority: -100

It does not work as expected because higher priorities are provided
by other sources.  My guessing is that a top-level stratum is missing,
priority above 10000 could mean that packages are not installed.

Denis
