Inerasable memory sticks - ROM
I heard something about Linux on memory stick which is more convenient to carry.
With DammSmallLinux it is possible to strip the OS download to 60- MB. However a memory stick is a rewritable device. It will not be so safe compared to a CD-R which can't be rewritten. Are there inerasable memory sticks (ROM)?
Disregarding whatever security measures taken if it is a rewritable device, a bad guy can always discover a solution to attack.
Any advice. TIA.
