Often, the applications run through workflows requires PATH to be set to point to where application specific software / modules are installed.
One way to set that is by setting the environment profile PATH as a profile in pegasus configuration. However, this assumes that the user knows the full system path on the remote nodes.
What would be good is a way for users to specify an environment variable KICKSTART_PREPEND_PATH that they can use to point the application specific directories. The value of this variable is prepeneded to the system path that kickstart see's before launching the user executable
if possible, would be good to have for 4.5.1 also
