Correct, its done on purpose. That lvm2 recipe resides in
meta-openembedded so we can not enable it in core. That must be done in
a local.conf or at the distro level.

The original fix can be backported to Rocko if it is in Sumo.

Please note, that patches should not be sent via an attachment. Please
use 'git send-patch'  instead.  Also, please use the
openembedded-core at lists.openembedded.org mailing list for core patches.
