Thanks for finding the problem! In the wiki, at
it does talk about this problem but doesn't anywhere say that it comes
up with this error. I'm very new to Fedora packaging so probably not
the best person to do it, but would someone be able to update the wiki
to say that this 'gotcha' creates a cpio bad magic error?
