151 The default value for the
152 <link linkend='var-DISTRO_FEATURES'><filename>DISTRO FEATURES</filename></link>
153 variable includes "bluetooth", which causes bluez5
154 to be backfilled in for bluetooth support.
155 If you do not want bluez5 backfilled and would rather
156 use bluez4, you need to use the
157 <link linkend='var-DISTRO_FEATURES_BACKFILL_CONSIDERED'><filename>DISTRO_FEATURES_BACKFILL_CONSIDERED</filename></link>
158 variable as follows:
159 <literallayout class='monospaced'>
160 DISTRO_FEATURES_BACKFILL_CONSIDERED = "bluez5"
161 </literallayout>
162 Setting this variable tells the OpenEmbedded build
163 system that you have considered but ruled
164 out using the bluez5 feature and that bluez4 will be
165 used.
