Really quite simple since NVM is so simple itself. Just used the standard curl + bash command to run the NVM install of the version of my choice (handling updates will have to come in a later version.) I use the install directory relocation option and that puts NVM into /usr/local/nvm rather than into the user's own folder. Then just source the newly installed nvm.sh file and run the NVM Node.js install command as usual. Voila.
There is also the ability to check out the repo and just use get to pull the current but if I do that how do I didn't install in the same fashion that this is installed?
