[OE-core] some simple questions/observations about package groups

[Robert P. J. Day]

  perusing package groups, and a few simple questions and probably a
couple things i can submit patches for.

  first, is IMAGE_FEATURES *exclusively* for selecting package groups
and not individual packages?  since core-image.bbclass reads:

# By default we install packagegroup-core-boot and packagegroup-base packages -

for that comment to read "packages" is a little ambiguous, yes?

  that same comment seems inaccurate as well, since it refers to
"packagegroup-base" when, below, it's actually:


CORE_IMAGE_BASE_INSTALL = '\
    packagegroup-core-boot \
    packagegroup-base-extended \     <-- see?

so that's just a quick doc fix.

  again, back at the top, we read:

# IMAGE_FEATURES control content of the core reference images

but it's not just the *core* reference images, is it?  in fact, the
list of available IMAGE_FEATURES in that file doesn't include
"splash", which is inherited from image.bbclass.  should that not be
in the list?  that also means that PACKAGE_GROUP_splash is available
to non-core images.

  finally, meta/conf/local.conf.sample also allegedly lists the
possibilities for EXTRA_IMAGE_FEATURES, but that list is noticeably
incomplete.  why not just refer the reader to core-image.bbclass,
rather than try to keep a current list in both places?

  lots of pedantry ...

p.s. as with other things i've put on my wish list, it would be great
if a variation of bitbake could list the available package groups.
