Nope, I was fooled by sstate once, so this time I tested with cleansstate and compared timestamps of the kernel when it boots - it is definitely the new one. And to make sure 'beaglebone-standard-build' extra suffix doesn't affect it, I increased the path length even further - that extra level with 333 is there to over-compensate, as it was failing before even with just 111 and 222 levels only... Looks like Gary was also able to verify it. But, you are right about vmlinux - it doesn't have those paths in there any more! I've seen them there when building with B != S, but they are gone when building with B = S. Wondering why.
