+Description:
+ cryptoloop on Linux kernel 2.6.x, when used on certain file systems with a block 
+ size 1024 or greater, has certain "IV computation" weaknesses that allow watermarked 
+ files to be detected without decryption.

+Notes:
+ - i am 99% sure that these issues still affect the latest kernels
+ - debian-installer only supports loop-aes and dm-crypt (i believe),
+   which are known to be not affected by these issues, so most users
+   are not affected
+ - perhaps a solution would be to disable cryptoloop?
+ - i have started an lkml thread: http://lkml.org/lkml/2009/12/2/232
