Summary and Info: It'd be neat to be able to optionally pass a string to pacman containing your reason/s for installing a package. Obviously, this would only act upon newly-installed packages, not upgrades that may also be part of the same installation; for example, assuming Firefox is out of date, running "pacman -Syu [--intent 'chromium\'s libpdf occasionally downloads instead of showing some PDF\'s' evince" will somehow store/bind the "intent" string to Evince but not Firefox.

Whether or not "intent" should be assigned to the already/newly-installed optional/dependencies by default is a bit of a thinker, as a user may use "whoneeds" to determine why, at least dependency-wise, a particularly odd looking package is installed on his or her system and determine the "intent" (perhaps from memory, assumptions made by Arch ["bash is a member of base group"] or the associated "intent" string) of the requiring package.
