solving file conflicts

[Erich Eckner <arch@xxxxxxxxxx>]

Hi fellow-archers,

I have two packages, A and B, which both provide the same file X. Is there 
a way to tell pacman to ignore file X in package B, so it is installed 
(and updated) solely with A? My current ideas are:

* repackage B (the official package), so it does not include X anymore -> 
tedious, feels unnecessary
* change packaging of A (unofficial package), so X is now called Y -> this 
will break a lot of configs, because X is hooked up in many places -> I'd 
like to avoid this option
* tell pacman to ignore X in package B (something like NoExtract - but 
except, that it is package specific and that it works as I need it ;-p)

regards,
Erich
