Huh. I'm going to miss the capistrano settings feature a lot.
But I had a lot of code that is parameterized with regard to settings,
such that there's a default value, but it can be overridden on the
command line -- and I'm going to miss that feature from the
default/standard recipes too.
I guess it can probably be substituted for with ENV, I'm gonna have to
think about it and experiment a bit.
But, hmm, some of the standard recipes are indeed using capistrano
'settings'. For instance, from: https://github.com/capistrano/rails
Some rails specific options.
set :rails_env, 'staging' # If the environment differs from
the stage
So there are still Capistrano 'settings'--they just can't be set or
overridden on the command line anymore? This seems unfortunate, it
makes Capistrano settings a lot less useful. Perhaps some recipes will
start using ENV instead of capistrano settings, so that they can still
be set/overridden on the command line -- but then what's the point of
capistrano settings?
I wonder if there's a clever way someone can figure out to reintroduce
the possibility of setting capistrano settings on the command line, even
within the Rake wrapper. It might be a good idea.

Well, the new Capistrano is based on rake so you have a few options.
One is the use of environment variables. You can set the before hand or
you can specify them on the command line:
cap stage task VAR=foo
Access in the code is through the ENV Hash:
ENV['VAR']
This is actually what I do and I do it the following way: I put accessor
methods for environment variables in a module. This allows me to add
code to check for definitions and make sure I warn the user if the
parameter is really needed:
module EnvironmentOptions
def var
return ENV['VAR']
end
end
