Hi all,

sometime ago I downloaded and installed cfs on my workstation.  After
testing it, I still don't get the point of cfs:

In a normal Unix environment, if I want to avoid that other users read my
files I just have to set the file-access permissions accordingly and
that's it. Only "root" can still read my files, so I can encrypt (e.g.
with the "crypt" command) any files I do not want "root" to read. cfs
makes it a little more comfortable because I do not have to type a
password for every file I want to encrypt or decrypt, but then the
protection against "root" is lost because "root" can anytime go to my
mounted cfs-filesystem and read everything anyway.

So, am I missing something here? What's the point of cfs? How are you
people using it?
