Danger of rm -rf
I see that rm has the option "--one-file-system". Should that be the default, perhaps?
I once caused accidental damage by doing rm -rf chroot, where chroot had something else mounted in it.
(Though obviously the main problem described in the article is crap hardware. Hardware should always have a "reset to factory defaults" button. Hardware should never be brickable by software. Not even by malicious software.)
