Comment 6 for bug 1553017

ok. so I've reproduced this using
 http://bazaar.launchpad.net/~smoser/maas/maas-ephemeral-sniff/view/head:/README.txt
basically:
  ./get-maas-eph xenial.d xenial hwe-w
  ./tgt-boot-test xenial.d/root-image.patch xenial.d/hwe-w/boot-kernel xenial.d/hwe-w/boot-initrd

The issue is simply that /lib/open-iscsi/net-interface-handler is installed without execute permissions.

** note, 'hwe-w' above is a bug, which will be fixed very soon in maas images metadata so you'll have to use 'hwe-x'.
