Setting .local in the hostname allows containers to find their own fqdn.
Setting the short hostname to a full hostname isn't really how it should
be, but there seems to be no way to convince avahi/mdns to resolve the
short hostname to the full .local version otherwise.
# Hostname
-lxc.utsname = ldap
+lxc.utsname = ldap.local
# Use this root filesystem
lxc.rootfs = /containers/ldap
# Hostname
-lxc.utsname = template
+lxc.utsname = template.local
# Use this root filesystem
lxc.rootfs = /containers/template
