Some users think that this is confusing: https://bugzilla.yoctoproject.org/show_bug.cgi?id=7122
For current implementation of wic it practically means that it must be always run as "PATH=/usr/sbin:$PATH wic" on OpenSUSE systems.

This makes sense to me. Not sure how easy is to do it as I suspect that not only parted is used this way.

BTW, this approach conflicts with this feature request: https://bugzilla.yoctoproject.org/show_bug.cgi?id=6558
So, should wic rely on system utilities or not?
If it should not then what would you suggest to do with #6558?
