Recommend me a live USB distro please?
 

I haven't checked the live-USB scene since Knoppix and PCLinuxOS were big 15 years ago. Now I think I something like that would be handy to have around.

What would be a good distro to run from a USB drive (no HD installation) these days?

If your PC is over a year old, Knoppix 8.2. It's still the best at doing what it was designed to do, before any other distro, run from live media.

I haven't used knoppix in almost that long. Any live/install CD will do - Mint, Fedora , whatever. I keep an old 4G USB that I use to test - it has whatever was last installed on one of my PCs.
Just connect to the network and install anything missing. Simple.

Hi,

since you seem to be a Slackware user, why not stick to that? Eg

Evo2.

yes, I would also suggest you the one you like (prefer).

Antix - MX Linux

(Reconfigurable, persistence, load to ram, etc, etc.)
