Alan Orth	ae10677b65	roles/common: Specify default apt_mirror for fallback in sources.list template ... New hosts often fail due to not having an apt_mirror, because there isn't one defined for their group and their host_vars haven't over- ridden it. We want new hosts to deploy successfully, so let's just use a default apt_mirror if there isn't one defined. Rather have a slow mirror than a failed deployment. And in any case, Linode can download from KENET's mirror at 10MB/sec. ;) Signed-off-by: Alan Orth <alan.orth@gmail.com>	2015-06-04 21:57:11 +03:00
