Comment # 13 on bug 1162581 from Jiri Slaby

While the fix is correct, there are two issues with the test:
1) on x86_64, it calls get_kernel_version on vmlinuz, not vmlinux (see
ls+sort+tail -1). It should use Image-* on arm, because:
2) we consider moving vmlinux to a separate package in bug 1166406 and the test
would blow up again.
