Tips:
  * no ''--source'', so wic will generate empty partition

Put ''/opt'' on separate partition:

<code>
part --ondisk mmcblk0 /    --source rootfs --fstype=ext4 --label rootfs --part-name rootfs --part-type B921B045-1DF0-41C3-AF44-4C6F280D3FAE --active --exclude-path opt/ --fixed-size 2G
part --ondisk mmcblk0 /opt --source rootfs --fstype=ext4 --label opt    --part-name opt    --part-type 0FC63DAF-8483-4772-8E79-3D69D8477DE4 --change-directory=opt --fixed-size 2G
