[oe] Package selection problems

[Dmitry Eremin-Solenikov]

Hi,

I recently stumbled upon a problem that looks more like a BitBake bug for me.
Using bitbake 1.8.10 and current org.OE.dev branch, I did the following:

Added PREFERRED_PROVIDED_virtual/kernel = "linux" to conf/machine/tosa.conf
Added DEFAULT_PREFERENCE_tosa = "1" to packages/linux/linux-2.6.28-rc6.bb

Then untill I added DEFAULT_PREFERENCE_tosa = "-1" to all recipes from
linux-2.6.14 till linux-2.6.21 (more recent ones just contain
DEFAULT_PREFERENCE="-1"), calls to bitbake linux, bitbake virtual/kernel and
even bitbake linux-2.6.27+2.6.28-rc6 tried to build both 2.6.27+2.6.28-rc6
recipe AND the recipe from 2.6.14 -- 2.6.21.

Is it an expended behaviour, is it some misconfiguration on my side or what?
