Gentoo GNU/Linux LiveUSB
Not long after buying a 10Gb ASTONE USB Mass storage device, I decided to turn it into a portable OS. Naturally, I chose Gentoo :)
One small hitch that I came across was the fact that busybox was failing to compile. This is how I fixed it.
emerge --sync
emerge binutils
emerge busybox
Now all I need to do is get wireless support/war-driving tools and some other rescue utils installed and noone will be able t stop me!
Have I ever told you that I love using Gentoo? :P
