I own a VPS but it runs centos. Reading the tutorial you linked above, im assuming you can only really do it with a sabayon OS, or gentoo.
I still don't fully understand how equo works. Is it based off portage but instead of downloading source, it downloads a precompiled version?
Is it similar to deb/rpm in the fact that all the source code is in the package (so you can get 5mb+ packages) , or is the package file just a few kilobytes that tells the operating system where to download the dependencies from?
