Not necessarily. The way our rootfs construction works, it has to be done via 
some package management backend, but many people don't want/need it in their 
final image. FYI some image recipes default to adding the package-management 
feature but core-image-base clearly does not.

It's actually easier to enable this than Khem suggested, however. The default 
Yocto local.conf contains a line that sets EXTRA_IMAGE_FEATURES - just add 
package-management within this, and you'll get package management in your 
image. (FYI the reason his example probably didn't work when you tried it is I 
think you may have left out the initial space - the list is space-separated 
and _append does not add a space beforehand.)

Cheers,
Paul
