One thing I noted is I added that line to the two recipes in question. When I [re]built my target image with these changes in a tree that I had just built using only sstate, it kicked off a ton of tasks (~6000!), and it seems that it's now rebuilding everything from scratch, not just unpacking the kernel. Once this finishes, I'll try another rebuild from sstate to see how that works, but it sure looks like it's doing a lot more than necessary. Is this to be expected? -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
