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?
