I cannot reproduce this using MAAS 1.9.3+bzr4577-0ubuntu1 (trusty1) and Juju 2.0-beta9-xenial-amd64 and LXD containers. I've deployed 5 nodes, each with 3 LXD containers. I double checked /etc/resolv.conf inside the containers, and it was as expected - containing both nameserver and search, like on the host. Pinging any node's FQDN or hostname worked the same inside containers as on their hosts.
