It need not be a single one, it could be a script. For instance, I once
ran an "update" script without checking that _my_ version of U-Boot
would be used. It used some ancient version which turned the board
(temporarily) into a doorstop.
Stupid? Yes! But would such checks (e.g. to "mw") have avoided the
problem? I doubt it. Probably I'd just have typed "yes" without
checking.
BTW, after accidentally erasing the environment variables U-Boot will
(likely) still start up, so it's really not that critical, is it?
Just my 2c.
Best regards
Markus
