Description of problem:

When installing Fedora 15 on x86_64, and an encrypted swap partition is selected to be used, there is no choice offered for fixed passphrase key vs. ephemeral (random) key.  Once user selects 'next', installer wants user to make up a passphrase, and there is no choice offered for a no-passphrase random key type here as well.  i.e. it will set /etc/crypttab to use some passphrase for field 3, instead of /dev/urandom.


Steps to Reproduce:
1. Install Fedora 15
2. Manual disk install on a normal SATA disk 
3. Do anything to make multiple partitions.
3. Select anything for the root.
4. Select a partition to be swap.
5. Select 'encrypted'.
6. Select next.
7. It wants a passphrase.
8. User wants to use disposable /dev/urandom key managed by dm-crypt.
  
Actual results:

Have to select a passphrase, and change /etc/crypttab later, or just set the whole thing up later.

Expected results:

A checkbox that says "use random (no passphrase) key for swap "
