Re: [Fab-user] using execute fabric command does not work as expected

[Jeff Forcier]

Please check the usage docs on the execution model - I think what you
want is to remove @roles from your function and instead give the inner
execute() calls 'role='staging'.

By putting @roles on stage() you're telling Fabric to run that task
once per host in the role's runlist - instead you want stage() itself
to just run one time "locally" and for the inner execute()s to handle
connecting per-subtask. Thus the role= kwarg to execute().
