A live cd is read-only and is also something I did for a while in my teenage years. Knoppix, Insert were examples and STD was another aptly named one as it contains outdated tools that really need to be upto date, otherwise they can do more harm than good. Scarily it is still downloadable and quite a dangerous but equally interesting learning tool. Comes with mozilla firebird that starts super fast and uses twenty something meg of ram, lol. There was also a guide to build your own OpenBSD live cd with X/packages. However, considering OpenBSD replaces it's whole base every upgrade with signed binaries, then you get all of that for free. You can even double check the bios with flashrom (less so on laptops), bootloader, signing keys, packages etc., if you want to. If this effort is really worth it, then it probably makes more sense than trusting someone else to package up a usb linux distro or CD.
