[StarCluster] USERDATA_SCRIPTS not running with addnode

[Cedar McKay]

Sorry to bump myself, but this is really the biggest difficulty I'm having with starcluster at the moment. It makes it difficult to use the addnode function, and even harder (impossible)  to use the Elastic Load Balancer.

As a general question, is there a place other than the USERDATA_SCRIPTS that I could use to execute scripts on each node's boot? I'm thinking of /etc/init.d on the boot image, or something like that, but I've been reluctant to modify areas where I suspect some starcluster magic might be happening.

As an aside, is there a better place to mount a volume? I didn't dare touch fstab because I figured it might be generate/changed by starcluster depending on the cluster config.
