[yocto] Best way to remove DISTRO_FEATURES?

[Neuer User]

Probably solved. It should be

include conf/distro/poky.conf

instead of

include poky.conf.

(Stupid newbie error).

Now bblayers.conf has been automatically updated to "6" again and the
system only recompiles a few packages. Should be finished in 10 min or
so. :-)
