Note that with this setting, "you" can thrash whatever is in /dev/sda
through /dev/sdb (write access). Besides "everyone" can peek into
/dev/sda2 and /dev/sdb1.

And by "you" I'm talking about any program running on your behalf,
i.e. an executable attachment to this mail which your mail reader
might let through, or a LaTeX class c&p'ed off the Interwebs.

This is not to scare you: just to help you tune your awareness
towards such things.
