Installing Gentoo Linux on a USB Drive is very easy… But it’s consequences are even greater! In fact, it is the same with any OS installed on solid-state drives. When any circumstances occur, favoring the unpleasant direct reboot of your machine, the inodes get screwed big time, or sometimes, not. That all depends on luck. I have experienced this the hard way. “Experience is a soft teacher when you learn from other’s mistakes, but it is a hard teacher when you learn it from yourself.”
