is there a guide somewhere to *all* of the solutions for encrypted
filesystems under fedora?  i haven't set one up for quite some time,
but i'd like to know what my options are.  for example, AIUI, there is
also the ecryptfs technique which is different from the above, yes?

how does it differ?  is one technologically superior to the other?
can this encryption be done in place on an unencrypted filesystem?
and can anyone stop the new england patriots juggernaut?  so many
questions ...
