We just put up a Rails2 image running OpenSolaris on EC2.
This is the real deal, Rails2, Ruby with DTrace support, Thin, Git, Mongrel, Mongrel cluster, sample SMF scripts and configured for a sample Rails application, OpenSolaris with ZFS on the root disk, MySQL, and Postgres.
OpenSolaris includes the Image Packaging System(IPS) which makes it trivial to add more software to the system.(for example, need AMP? just utter "pkg install amp-dev" )
It's available here
