the old "rvm requirements" was just set of text to display about what is required, with time it got more and more conditional, but never was doing anything, by following the automation path we have taken some time ago we have turned requirements into code that does all the "right" things users should do to get the libs needed for ruby, it is often more then just running single command.
as it all automated now we have created the "autolibs" flag that control level of automation by using the "disabled" level it should be obvious - rvm will use no automation, it's all up to you - we assume you know better.
