     Sure /home is the first place one thinks of encrypting and /tmp is 
the second, together with possible other fancy dirs. Encrypting passwd 
and the like would just add a little of security-through-obscurity by 
even hiding the usernames; this is why I considered /etc as a third 
(non-obvious) thing to encrypt; /etc also contains every local 
configuration, and it might make sense to hide it all.


     To simplify, all of /home and /tmp aren't really part of the OS. 
The OS can boot without them. All the rest is the OS and is the same as 
any other install of the same OS; and there isn't any reason to encrypt 
something which is published and widespread.
