I tried to shift the discussion to "how does cfengine pass data to
child processes." Right now this happens through the command line,
which has many limitations compared to a regular data exchange
protocol such as the one I proposed.
Specifically for $(allclasses) this is not necessary, but maybe next
something from cfenvd will need to be passed to a child process, or
better knowledge of cfengine's internals (e.g. to tell the process if
it's started from shellcommands: or processes:) will be needed. How
do you distinguish between all the data cfengine could pass down?
Instead of doing this ad hoc, it's better to set the standard now, I
think. Of course it's not my decision, I'm just offering some thoughts.
