tslib is also requested on devices where kernel driver returns too much noise, tslib can filter that, evdev needs separate filter like http://atrey.karlin.mff.cuni.cz/~metan/evfilter/ but that isn't integrated in OE. > * xserver-nodm-init: the two versions are quite distinct.

MySQL and PostgreSQL are not in oe-core so it cannot be replaced with simple PACKAGECONFIG option in oe-core recipe, but I also prefer to share such .bbappend somewhere instead of every distribution reinventing the wheel when trying to enable something as simple as db in qt. > * meta-oe/recipes-multimedia/gstreamer/gst-ffmpeg_0.10.13.bbappend > Builds against external libav instead of using the builtin copy of ffmpeg, > apparently for better performance on ARM (and presumably that is not the only > benefit).
