Hi Trevor,
Thanks for the new version.
We have some test failure as the wic tool is not found in path. I
believe we already discussed that previously, but I'm not sure what was
the conclusion.
Poky - The Yocto Project testing distribution
Running '. ./init-build-env; wic create directdisk -e core-image-sato -o
${BUILDDIR}/tmp/deploy/wic_images/qemux86/directdisk/core-image-sato/' with
output to /srv/pokybuild/yocto-worker/wic/build/build/command-1-cmds.log in
/srv/pokybuild/yocto-worker/wic/build/build
/bin/bash: line 1: wic: command not found
https://autobuilder.yoctoproject.org/valkyrie/#/builders/15/builds/3190
I will let other tests finish, so we can have an overview of the
situation.
Thanks,
Mathieu
