Re: Description of the Journaling topology

:What if the journal is for an encrypted disk?  It would probably be 
:desirable for the journal data to be encrypted in that case, especially 
:if the stream was a socket to an offsite machine.  It might be necessary 
:to store key data in the journal; depending on just how the encryption 
:is done.
:(Sorry if this sounds like I'm playing devil's advocate.  I really meant 
:to ask this question earlier, but I didn't really (and don't now) have 
:the knowledge to ask it in a more detailed/helpful manner.)

    Well, that's a pretty good attempt but I would counter with: "But wouldn't
    it be easier just to have an application take the journaling stream and
    encrypt it?".  Remember, the journal is just a descriptor, it can point
    to anything, including a user program.
