That's one of the things I asked a few messages ago. Some people on
the list were saying that it'd be "really hard" and would "require a
lot of bookkeeping" to "fix" permanently-D-stated processes... which
is completely different than "impossible."
Nothing is "impossible".
Maybe where you live, but in my world some things are most certainly
impossible. Getting a 1MHz CPU to run at 1THz is impossible. Having the
kernel automatically install the latest firmware for a buggy device, without
actually having the new firmware file, is impossible. Turning your 17" LCD
monitor into a 50" HDTV is impossible.
Cracking SHA-256 isn't "impossible", it just
takes more computing power than exists on the face of the planet.
Thanks for proving my point. That's a perfect example of the difference
between "hard" and "impossible."
Call it "infeasable" if you like. It's theoretically possible, but the
amount of work and the overhead involved just are not realistic.
Again, that was one of my earlier questions, since some people here were
saying "impossible" while other were saying "really hard."
