No worries. These are actually good questions!

Yes, we recommend keeping the "-l release=trusty" in the command. The
jsub process will currently give a warning on stderr if no "-l
release=..." argument is present. Setting "-l release=trusty" is the
same as the default today, but it will keep you from seeing that nag
message.

The jsub, jstart, and qcronsub commands are all actually the same
program, so the "-l release=trusty" advice applies to any of them that
you may be using. The only difference between these three names is
default arguments:

* jstart ... == jsub -continuous -once ...
* qcronsub ... == jsub -once ...
