I have been surprised over the last few days at the number of packages
being built for the core-image-rt target, which for reference is as follows:

#
# Copyright (C) 2010 Intel Corporation.
#

DESCRIPTION = "Real-Time Linux Image"
DEPENDS = "linux-yocto-rt"

require recipes-core/images/core-image-minimal.bb

IMAGE_INSTALL += "rt-tests"

LICENSE = "MIT"


The only dependencies of rt-tests are:

DEPENDS = "linux-libc-headers eglibc"


Building core-image-rt schedules 3154 tasks, and among them are things like:
lttng-viewer
gst-plugins-base (bad, good, etc)
gtk+
libogg
libtheora
owl-video
clutter
libglade
librsvg
mesa-demos
x11-perf
xvideo-tests
etc etc etc

I noticed my local.conf contains:
EXTRA_IMAGE_FEATURES = "tools-debug tools-profile tools-testapps
debug-tweaks"

That hasn't changed in a while, but perhaps those features now pull in
more than they used to? Or if they don't, are we unintentionally pulling
in a lot more packages for what is essentially a minimal image?

Thanks,
