A quick google reveals that the "standard" way to do it is the loopback
encryption filesystem. You have a regular filesystem which contains an
encrypted file which is mounted over loopback.

SecurityFocus says it's vulnerable to a replay attack, though no exploits
are known and this would be difficult; nonetheless, it's a design flaw.

I'm not particularly crazy about the idea because it seems like a really
lazy way to support an encrypted fs. You've gotta' be taking a pretty
decent performance hit. OTOH, it does sound simple enough to be reliable.

And, man, I am lazy...

There is CFS also, however it appears to have become depreciated or at least old...

I am rather disappointed if that is the case. Although, I'd be surprised if a modern file system like RiserFS or even ext3 (eventually) doesn't have someone working on a build model that supports some sort of encryption.

Quick google search shows possible other alternatives
