I am looking to turn a 8Gb USB into a bootable drive with a minimal OS. All I want is an OS that will allow me to use vim, nothing else (no internet/any other services). I basically want to turn a USB into a digital typewriter.
I was able to make a bootable semi persistent Ubuntu USB using syslinux and uNetBootin on my mac. However, Ubuntu seems too bloated.
What would be a good OS for my needs? Also, could I make a persistent bootable USB with it?
