[erlang-questions] running multiple instance of app release
Mon Apr 28 21:30:09 CEST 2014
After some arm wrestling I discovered the "real" problem, operator error.
As it turns out the release works just as I wanted. I am able to start the release with "-sname nodeName -config nodeConfig" with no issue at all.
Sorry for the noise.

Prior to this change my deliverable was basically the ebin, maybe the include, directory for my application that would be located in /usr/lib/me/lib/myapps/.... To run the application I would export ERL_LIBS as /usr/lib/me/ the start the node with -sname -config, etc. and off it went. In this way I can run the application many times with different -sname args.

It appears that the generated script for starting/stopping the application does not support command line options/arguments. Without being able to set the node name how can run the same app more than once.
