The whole point of the design is to make the configuration process invisible
to the user; they don't need to know even that this file exists. Both the
file and its contents are implementation dependent.

One idea I had was to put it under the mount point so it is not
visible/accessible. As far as putting it in /dev/db, you can
always do that.

Ah and I forgot one more command that should be supported chflags, and that
takes another bit.

BTW, most of the code needed to do this is already in ptyfs. So it would take
less than a week of programming time to have a working prototype.
