[OE-core] [bitbake-devel] how to store a modification of a bbclass in the poky layer in my own layer.

[Davis Roman]

Hi Christopher,

I am very intrigued by your response.

Initially I had mentioned that the 'bitbake-layers show-layers'
command indicates that my layer, meta-hon-grip, has a priority of 8
which is among the highest while the meta layer only has a priority of
5.

However, now that you mentioned the bblayers.conf file, I see that the
meta-hon-grip layer is defined after the meta layer.

Therefore it appears to me that my bblayers.conf contradicts
'bitbake-layers show-layers'

Could you please help me make sense of this?

Thank you,

Davis
