Adding Richard and Guillaume.

Hi,

it seems seems edison-image.bb sets ROOTFS as empty:
http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-edison/tree/meta-intel-edison-distro/recipes-core/images/edison-image.bb#n17

so do_bootimg won't depend on ${PN}:do_image:${LIVE_ROOTFS_TYPE}. That
dependency would, I think, create the folder you mentioned.

Maybe the patch wrongly assumes that if ROOTFS is empty, we shouldn't
add a dependency on "do_image.${LIVE_ROOTFS_TYPE}" at all since It
looks like edison-image.bb still depends on
${PN}:do_image.${LIVE_ROOTFS_TYPE} even though ROOTFS is empty. I
haven't looked too much into why edison-image works this way.

Wow, that got messed up, let me retry.

Accidentally I refreshed poky and rebuilt. The image-live
(do_bootimg) fails when building hddimg with the following:

mkfs.fat 4.1 (2017-01-24)
WARNING: exit code 1 from a shell command.

The reason is that the directory deploy-edison-image-image-complete
doesn't exist at the time mkdosfs want to write. However after
completing the remainder of image live the directory does exists.
Consequently, running bitbake a second time image-live succeeds.

I've tried various thing including expressly creating the directory
before mkdosfs, but nothing worked. It seems I don't understand how
it is supposed to work in the first place.

However, I managed to trace back the issue to this commit 91e4a1c1
"image-live.bbclass: optional depends when ROOTFS empty".

Reverting this resolves the issue.

Any idea what could be wrong?
