Yes, that's what I ended up doing, so it's nice to know I'm on the right track.
However, when I explicitly added "hddimg", I found that Syslinux was still configured for live image, with "boot" and "install" menu options. I found some code in image.bbclass that looks like it forces "image-live" if either "iso" or "hddimg" is included. I can of course hide that by setting various Syslinux options, but how do I get a plain hddimg that just boots up and runs, without any support for an "install" option in the kernel? Is that normally done with "wic" and a minimal .wks script?
