Encrypting a filesystem is useful if you loose your
laptop/flashkey, when you aren't around when the people find
your harddisk. However an encrypted filesystem is useless
going through TSA/DHS when they can just say "give us the
passwd or you're going to Gitmo". In this case you need
plausible deniability - "what encrypted filesystem? there's
no encrypted filesystem, that's just random deleted files".
I notice that you can have plausible deniability, but as you
would expect it's proportionately more difficult to setup.
