You should see output printed here in log.do_rootfs for the image you are building. In case you're unaware, you can find this in the directory pointed to by the T variable for the recipe, the following command will show this to you: bitbake -e your-imagename | grep ^T= As an aside, we do want to change the bbwarn/bbnote/bberror etc. shell functions to output to the UI just like the python equivalents do, it's a known issue that they do not. There's a bug open for that (assigned to me as it happens): https://bugzilla.yoctoproject.org/show_bug.cgi?id=5275 I should really get that one sorted out for the next release.
