what if we created some kind of udev/blkid/etc. approach?  ie. we
write some custom udev rules to manage a special directory/update
files/touch files/run scripts/etc... as the system changes udev would
make sure AIF knows what the actual state is.

i'm not super adept in the rules syntax, but i know enough to be
dangerous.  it seems like we could leverage it in some way to take
care of all the dirty work... AIF just needs to monitor the <insert
here>, and verify against an identical copy it creates during the
install.  this would also let AIF adapt to any outside changes made my
the user with some grace.
