This is taking some time due to unrelated issues, but in the meantime:

What are the thoughts on having a similar --exclude-path mechanism for
the standard rootfs building? IOW, the do_image_ext4 and friends?

Our usecase is that we use wic to build a complete image, using
--exclude-path to group things into partitions. And then we want to
build a regular ext4 image and use this as an update to the device, and
in this case we want the same content as wic generates, but in a raw
rootfs file instead.

As an alternative to do_image_ext4, it might be possible to use wic to
build a rootfs raw filesystem instead of a partitioned file, but I
haven't looked into that yet.

Thoughts?
