Live ISO from USB drive
Does anyone know how to take a live system ISO and put it onto a USB stick to boot from rather than burn to a CD/DVD? I know it's possible in general because the SystemRescueCD describes how to do it with their ISO (and I've made it work). I'm just wondering if this will work in general or if each distro will have different rules/requirements to do it.
The trick is the initrd needs to have USB drivers built into it so that the system can recognise its own drive beyond the the ramdisk stage.I know Knoppix is difficult to set up like this. It really depends on the distro. If you don't mind which distro you use I can recommend Slax, and many members recommend DamnSmallLinux. Both have USB install mechanisms.
