I enabled the file system encryption upon install of Fedora 17. I would like it to auto decrypt like Ubuntu does. I want to only put my password in once, but still encrypt my files. Can anyone here help me?

Note: In Ubuntu, you can chose to encrypt your home directory. When you boot your system, Ubuntu automatically decrypts the home directory for you before you log in.

Edit: If it is not possible, how do I disable the disk encryption without reinstalling Fedora? I already have a lot of programs that I have added and I don't want to go through that whole process again.

Ubuntu uses a different encryption technology to encrypt the home directory (ecryptfs) whereas Fedora has whole-disc encryption. With ecryptfs, only data inside a filesystem (or directory) get encrypted (ala windows xp pro) leaving Filesystem stucture data exposed.
Whole-disk encryption (aka LUKS) (as the name suggests) encrypts the entire filesystem, leaving a malicious HDD thief unable to distinguish data from random noise, or even to see how much data may be on the hdd. With ecryptfs, on ubuntu, your user password is your key, and thus by logging in, you unlock your home directory. With LUKS, it is possible to create a key, put it on a USB flash drive and use that to automagically decrypt the volume.

I found basic Instructions for the LUKS flash keys here:
