Re: eCryptfs vs LUKS
LUKS is block device encryption (e.g. /dev/sda1)
ecryptfs is file level encryption (e.g. /home/user/Private/). You mount a folder, and every file created in that folder will be encrypted individually. If you umount the ecryptfs folder, you will still see the files, but the contents will be garbled.
There are several advantages to this approach, but the main one is that the home directory for each user can be encrypted with a different key.
With LUKS, it is only possible to encrypt the home partition, or with more work, create an encrypted partition for each user (with fixed size, less flexibility).
AFAIK, ecryptfs is available on Fedora as well.

It really didn't mention game performance but of course that will be largely unaffected, especially if your games are installed to /opt or other places outside your home dir. Wine games might suffer some though depending on how I/O intensive they are.

There also have been talk of nvidia opening access up the AES engine found on the GF 8 + to the Cuda toolkit.
Aso if you own the book GPU Gems 3 there is a dedicated chapter to this subject.Last edited by deanjo; 08 December 2008, 02:12 AM.

Encryption would be really cool, but getting locked out of your data is unacceptable.

I like no one can see what files I have, so I say with LUKS
