Hi Chris,

My apologies for the long delay on this. Currently the easiest way to
do this is via a plugin that iterates through all the nodes and adds
entries to a file in /etc/profile.d (e.g. /etc/profile.d/scenv.sh).
Your environment would then be loaded anytime /etc/profile is sourced.

Here's an example of a simple plugin that would do this (untested):

I'm working on adding the ability to specify a user data script for
all of the nodes so that scripts can be automatically run on node
start-up independent of StarCluster. Once this feature is added you
could create a simple bash/python/perl/etc script to do this, and any
other simple tasks, as soon as the instance boots...

HTH,

~Justin
