Doesn't works in coreos

[ebergonzi]

The (very) persisting error:

tagged skynetservices/skydns docker-registry.afip.gob.ar/dearin/skydns because i need skydns over etcd (skydns2).

docker run --rm --name skydns -e ETCD_MACHINES='172.17.42.1:4001' docker-registry.afip.gob.ar/dearin/skydns:1.0

this is likely not your cause, but when I was running skydns and getting this error, it was because I didn't have a) a hostname set, and b) the hostname IP address was not in my /etc/hosts file.
