An update proof way to customize icons (and other things)?

[robgitnyc]

So, for the sake of identity of my instance, I want to replace some images at ~/live/app/javascript/images/ and ~live/public/packs/media/images/. However, I am wondering what is the best way to make these images and icons persist through updates. One way, the most "primitive" so to speak would be to just save the folder and restore customized files after updates. Is there other way?

I remember other Rails app (Consul Project www.consulproject.org) that had an override method such as that ther was a ./custom folder for every folder that contained files that could be customized, such as ./locales, ./views, etc. However that app uses Capistrano for deploying updates. I loved that way of updating because deploying changes to production was so smooth, you just had to run cap deploy <branch name> from your dev environment and that was it. Any chance to design a workflow like that? I would love to contribute to that but I barely know html/css and some javascript.
