Why start "etcd" not "etcd2"?

Hi!
I were looking at your code as solution for building auto healing etcd cluster on top of ASG.

I started to wonder why you call etcd not etcd2? https://github.com/crewjam/etcd-aws/blob/master/etcd-aws.go#L213
At least when I check in CoreOS alpha (899.11.0) the etcd executable starts the older version and etcd2 the new.

Might be outdated, I had to modify and recompile

[crewjam]

because in the Docker container we are carrying our own etcd which is version 2.

Not sure how to clear that up? perhaps build the etcd binary as etcd2?

PRs/suggestions welcome. :)
