[Bug 237721] Re: Secure attention key

[Rodolphe Ortalo]

CTRL-ALT-DEL also means "shutdown" on many Linux distributions when hit
on the (text-based) console, so using this shortcut does not seem
adequate to me due to the caveat of *not* using it when login in on such
terminals. (And I find this useful too to allow operators with physical
access clearance to shutdown a server while not having logical access to
the computer, e.g. in emergency situations.)

Anyway, for me, the primary issue/wishlist is not chosing the "right"(tm) combination of keys but rather *displaying* it at the login prompt in a more or less unified way. Wouldn't it be an improvement to display a standard help message on most graphical login managers to clarify this unknown functionality of our login process: SAK-like behavior?
At least, it may be nice from the security marketing point of view. (IMHO, we already do it, so let's just inform users about it...)

BTW, a well-designed trojan horse may try to mislead users about thekey
combination too... ;-)
