How can I specify a machine defconfig for a linux recipe?
For example, if I set
# kernel provider
PREFERRED_PROVIDER_virtual/kernel = "linux-omap3"
and try to build my machine, I get the following errors:
ERROR: Function failed: Fetcher failure for URL: 'file://defconfig'. Unable to
fetch URL from any source.

I solved this one.
Turns out, since I defined a new machine called overo-fire-chestnut43, I had to
also create a folder called overo-fire-chestnut43 to hold the defconfig file as
follows:
meta-gumstix/recipes-kernel/linux/linux-omap3/overo-fire-chestnut43/defconfig
I recall, the trend was to move away from user supplied defconfigs, and have it
get generated automatically by the build process, and then specify some hints.
Is there any example of how I can modify the existing meta-gumstix or any other
meta-layer, to get the defconfig to get generated automatically?
Are you thinking about the linux-yocto config fragment support ?
Or maybe something else ? If you were thinking about the fragments,
it would only replace your defconfigs directly when you use a linux-yocto
kernel tree (and it's included meta branch with configuration frags).
In that scenario, you only put your board specific fragments on the end,
and let the rest be constructed.
When I return home next week, I will have some patches for 1.3 that make
the fragments apply more easily to any git repository, but in either
case (1.2 or 1.3), you'd still need to build up a series of fragments
outside the tree, or migrate to linux-yocto* for maxium re-use.
