For angstrom it's an IMAGE_FEATURE, since some images need it (e.g.
console-image) and others don't (e.g. initramfs).
Right not you can set ANGSTROM_PKG_FORMAT to 'deb' or 'ipkg' to create
images using .ipk or .deb packages, with no rebuild needed, changing it
halfway during a build and restarting bitbake "Just Works(TM)". Any
changes to how a packagemanager is installed must keep that
'automagical' feature. The only thing missing in Rods patch is to set
the packagemanager var in
conf/distro/include/angstrom-package-{deb,ipkg}.inc.
