When using a .wks.in file, the only place that the generated .wks file

.wks.in files can reference any number of bitbake variables, so it is
important to save the result.
below is an example of using the generated .wks file in the deploy
area. The full name of my generated .wks file was
core-image-minimal-ostree-uboot-ab.wks, but since you usually only
have a single .wks file per image you can use a wild card like:
cd tmp*/deploy/images/*
wic create --vars . -e core-image-minimal -s -m core-image-minimal-*.wks

Nothing should be writing to DEPLOY_DIR_IMAGE directly as it means its
not being managed by sstate and won't restore in a build from sstate.
There is an intermediate directory it should be written to and the
sstate code will put it into DEPLOY_DIR_IMAGE. For image classes it
might be IMGDEPLOYDIR but you'd have to check this task/code runs
between do_image and do_image_complete.
Thank you for the pointer. It works exactly as intended so long as the
dependency
is changed properly, and the correct staging directory is used.
There is no directory creation required because the do_image() takes care of all
that.
I'll send v2 of the series, but this this the only patch that changed.
Jason.
