This should ensure that the appliance image mount structure is
correct during image creation.

@dcavalca Please test this ASAP to verify this works so I can land this in Fedora before the next compose.

I'm not sure if this is a side effect of running in mock or not though.

It does look like a valid filesystem gets created and mounted on /var/lib/mock/fedora-rawhide-armv7hl/root/var/tmp/imgcreate-8_yhm7op/install_rootbtrfs.007 regardless of that error though, so it might be a red herring.

Converting the kickstart to run on x86_64 seems to indicate it works:

@dcavalca Can you try again with this updated patch?

I'm still getting the same error when building for armhf, but I think it's unrelated to the change you made. How did you get it to work on x86_64?

@dcavalca I edited the kickstart to switch from armhfp to x86_64 and then used an x86_64 mock root instead of an armhfp one.

Looks like the partitions are in the right order now:
