From 56eaad835dde784a963d8802f862d9827ec942ed Mon Sep 17 00:00:00 2001 From: Bob Fournier Date: Wed, 23 Aug 2017 17:15:34 -0400 Subject: Handle failure of carrier check in configure_safe_defaults() Configure_safe_defaults() should handle carrier check failures in the same way as the change that was made to dhcp-all-interfaces.sh in https://review.openstack.org/#/c/419527/. That is, it should ignore failures when cat'ing the carrier file.
