   Hi, thanks for the question. You should also check on Stack Overflow to see if you get more answers there.

   The requirement you describe is not possible with the current execution model of SSHKit, at least out of the box. You might be able to plug in your own custom runner to do this.

   In other words, instead of this:

   in: :parallel
   

   You could write this:

   in: ParallelIgnoringErrors
   

   And define the runner as follows:

   class ParallelIgnoringErrors < SSHKit::Runner::Abstract
     def execute
       # your custom execution logic goes here
     end
   end

   If you get it to work, let us know, and we can discuss whether this belongs in SSHKit and/or something that should be called out in the docs.

   Using test() rather than execute returns the result of the command rather than erring if it's non zero. test() is just a wrapper around execute() which sets certain flags on the command object (namely not to raise on exceptions) - depending on the nature of your failure this may or may not do what you want. See our examples file in the root of the project. (Sent from my Nexus 6, please forgive typos!)
