Rawhide composes are currently failing when creating ARM images, with this error:

DEBUG util.py:439:  Traceback (most recent call last):

e.g. https://kojipkgs.fedoraproject.org//work/tasks/7841/24887841/root.log (that's from https://koji.fedoraproject.org/koji/taskinfo?taskID=24887841 , the ARM minimal disk image compose attempt for Fedora-Rawhide-20180209.n.0 compose).

This is due to this commit to livecd-tools: https://github.com/livecd-tools/livecd-tools/commit/491a49ff9aedf5197af3e4dcb0f50351db3cddf0

which removed the exact method appliance-creator is trying to use. appliance-creator has to be changed to do...something else. Whatever it should be doing.

This is an automatic F28 Beta blocker: "Bugs which entirely prevent the composition of one or more of the release-blocking images required to be built for a currently-pending (pre-)release" - https://fedoraproject.org/wiki/QA:SOP_blocker_bug_process#Automatic_blockers .
