My final word is that you should give up trying to reinvent the wheel, and use a method supplied by the distro for mounting disks. It's not worth my time to play whack-a-mole here. As Dan said, "Usually I get paid good money to own software this hard, and I don't think you're worth making an exception." Indeed.
The solution is easy and obvious, but it involves backing away from stubbornness and accepting that the distro-supplied tools handle mounting inline with distro policy, and it isn't your place to reinvent things. Take a look at Gentoo Mike's post from a while back -- it's dead on. Besides, you haven't even begun to address issues #1-#3.
I believe this discussion is over. Goodbye Kovid. I wish you well with Calibre and that you can restore the security confidence of your users.
