wic: root: Add an opt. destination on include-path
Allow specifying an optional destination to include-path and make the
option aware of permissions and owners.
It is very useful for making a partition that contains the rootfs for a
host and a target Eg:
/ -> Roofs for the host
/export/ -> Rootfs for the target (which will netboot)
Although today we support making a partition for "/export" this might
not be compatible with some upgrade systems, or we might be limited by
the number of partitions.
With this patch we can use something like:
part / --source rootfs --fstype=ext4 --include-path core-image-minimal-mtdutils export/ --include-path hello
on the .wks file.
