Etcd v0.1.2 with a new dashboard

Etcd and CoreOS look really great, but I'm still missing a fundamental question. If I've got a set of CoreOS instances running on EC2 with auto scaling on, how does a new instance add itself to the cluster when it starts up? How does it know which other servers to associate itself to, and how do these server know to trust it?

Hm. Looks kinda cool - the TTL option for keys could be a very useful tool.<p>One question&#x2F;problem: I can&#x27;t find any kind of permissions&#x2F;separation&#x2F;ACLs for it. Yes, you can do authentication, but w&#x2F;o even basic POSIX style owner&#x2F;group&#x2F;world type permissions, this essentially becomes single-user, with all apps&#x2F;programs&#x2F;etc trusted and able to break everyone else.<p>Or am I missing something?
