This patch got a bit lost before the holidays but I've been reminded we
need to resolve it.

I think the one remaining issue here is the need to change the DEPENDS
of so many other recipes, likely not just here in this patch but in
other layers. I think if util-linux DEPENDS on util-linux-uuid that
might remove the need for those changes? That should still allow you to
break the circular dependency problem?

I suspect libuuid should really be maintained/built as a separate
software project given the dependency problems but that isn't my
decision, we just have to deal with it.

I am also worried this is going to break AUH and mean we have to
manually handle this recipe but again, I suspect there is little to be
done and we just have to deal with it.

Could you resend it with the above DEPENDS change if that will work ok,
refreshed against OE-Core since we have util-linux 2.36.1 now and then
hopefully we can resolve this.

Cheers,

Richard
