# Current implementation of updater can't remove package before replan and so we
# can't let updater-ng steal opkg-trans files. With dependency:
#   if not version_match then
# 		Package 'updater-ng' { deps = 'opkg-trans' }
# 	end
# this empty package should ensure that we correctly move packages from opkg-trans
# to updater-ng even with old version of updater. Unfortunately this won't work
# with downgrade.
# Note that because version_match was defined after package rename we can't use it
# to check version. But if it isn't defined than we know that we are using some
# old version of updater.
