The extensible SDK installation process (defined in populate_sdk_ext.bbclass) by default runs bitbake in order to install the sstate cache to the point where you can assemble an image, however at the moment it actually runs do_rootfs which is completely unnecessary. Probably the easiest way to fix this would be to stub out do_rootfs making it a no-op (e.g. by inheriting a class that does this just for this run).

FYI I've made a fix for this and am testing it now.
Fix merged to master: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=9a81ba764c31ae8e5af08c2bd672b2fbca46d497
Hello, Tested with latest commit: 505a82673ac2487df5ea343a6422c2fc47018831 on an Ubuntu machine. Steps performed: 1) ensure having a clean environment (i removed tmp dir) 2) prepare SDK: bitbake core-image-minimal -c populate_sdk 3) search for any do_rootfs in cooker log: ~/2poky/build/tmp/log/cooker/genericx86$ ls 20151022083315.log ~/2poky/build/tmp/log/cooker/genericx86$ grep rootfs 20151022083315.log Marking as verified.
