Re: Order of Execution

I believe is talked about once every three months.  I suppose the best
way to handle this is to create scope for the actionsequence.  Everytime
a new actionsequence is reached it gets push onto a stack of some sort. 
Once that particular cfengine script is done executing.  Then the
original actionsequence takes over.

The other way would be to change it for the rest of the execution. 
Which I can't see being useful.  If anything you might want to localize
the sequence for a particular script.

I know Mark went ahead and added the second pass of execution to
cfengine.  I believe my script takes advantage of this.

Add this to the wishlist.  Maybe in the next year someone
will be interested in developing scope.  Then again I could be totally
wrong.  If my time frees up I would certainly entertain taking this on.

Then again I am interested in what Mark has to say about this. 
Considering it might upset some of the cfengine core principles.  To me
this would be a much better way to handle this.  Considering how many
people want to do this.

actionsequence = ( shellcommands.firstpass shellcomands
shellcommands.lastpass )

Any they only want the class firstpass to be valid during the execution
of shellcommands.  Maybe this scoping would help.
