And, as I keep reminding people, if you REALLY don't want to expose your
passwords and configurations, the only safe solution is to drop into the
shell, and 'dd if=/dev/zero of=/dev/ad1'. 

This erases the hard drive. I then pull the flash and plug it into
my laptop and 'dd' over that, too. Then replace the CF card and boot up
on the distribution media to install a clean JunOS.

This will make sure RAS never gets a chance to read your config. :-)
