The following issues (from the last telecon) need comment from multiple people; please feel free to jump in with anything you want to say on these topics. 12) Mapping mountpoints to environment variables (see spec 5.5.12) 16) Process topology section needs review 32) POSIXApplication/Executable cardinality (=1 vs <=1) On issue 32, my feeling is that having the Executable as optional is a good thing since this permits the processing engine to derive the executable name from the overall application name and version. I've known the same application be installed with multiple different names across multiple architectures within the same overall organization, some of which are non-trivial to guess[*], so concealing that sort of stuff from users is a distinctly good thing in my view. (Very few users want to know, and sometimes there are details of the job running process which we would prefer them not to see either.) Does anyone strongly disagree on this point re cardinality?
