Suppose you are on the road, and you have your usb

However, on every "user friendly" distribution there are all kinds of
windows that pop up when you plug in the usb stick, but none of them is a
shell prompt. Worst of all, you notice that your stick is already mounted
read/write! This is on an unknown system that you know nothing about. It
might as well wipe your stick, or install a rootkit on it. How are you
ever going to know what the userfriendly police is doing behind your back?
That is why decent USB memory sticks have a write-protect switch on them;
regardless of how the system tries to mount it, if the write protect switch is
set the write line should be disabled and nothing should be able to write to
