[pacman-dev] [PATCH] Print error on duplicated database entries

13 Nov 2009

Some users reported duplicated database entries in /var/lib/pacman/local/,
for example, both foo-1.0-1 and foo-2.0-1 subdirectories existed. (Bogus
3rd-party scripts, backup?) In this case pacman reported no error and its
behaviour was mysterious.
...
From now on, pacman detects this situation and prints an error message.
