True, it can relief some of the pain. Of course, there's still
pain after a reboot - and sometimes, you need passwords at
boot time (if one or more boot scripts need them). Also, I
presume keyagent isn't storing all its state on disk, which makes
it not a solution for cluster environments. Which of course
you do you, to minimize downtime in case of failures, don' you? ;-)
It's really a hard issue, and probably not really solvable.
Having someone available all the time at the console usually
isn't possible. Doing away with passwords isn't the solution
either. So, passwords will be have to stored in files sometimes.
OTOH, we shouldn't abandon all hope. If you can't rely on file
system security, then nothing will be save anyway. /dev and
/proc will be great sources of information, and most likely,
your write permission won't hold either.
