Ha! openjdk-6-jre- {headless, lib} both of version
6b38-1.13.10-1~deb7u1 depend on one another! ;-)

Well, yes! I think that Debian's APT, dpkg, apt-clone, ... within the
context of how they compare to other packaging systems, their essence
and functions has the potential to become very beneficial to the
Debian and Linux culture. The other day I heard the author of Qubes OS
himself say that his project was not the be all and end all of Linux
security, that the only way to use a computing device with some of
that thing they used to call "privacy" is not to ever connect it to
the Internet (even physically removing the pertinent hardware and
compiling the kernel without networking libraries if it comes to that)
and I remember Linus Torvalds himself saying once publicly that he
never connects his work horse computer to the Internet. He was even
profusely making faces while he did.
I think Qubes OS in a sense is an aberration, too wasteful
operatively and I do think that you could run the same box in
air-gapped and exposed mode in the "touch of God" way I already
explained.

... and I don't know if you care about exact arithmetical computing,
the mind-body link, corpora research, ... but as a way to thank
you/the Debian culture I will let you know what came out of your help.
