           Summary: RELNOTES - Encrypted swap and non-root filesystem
                    support
           Product: Fedora Documentation
           Version: devel
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: normal
         Component: release-notes
        AssignedTo: relnotes@xxxxxxxxxxxxxxxxx
        ReportedBy: mitr@xxxxxxxxxx

FC6 provides basic support for encrypted swap partitions and non-root
filesystems.  To use it, add entries to /etc/crypttab and reference the
created devices in /etc/fstab.

An example /etc/crypttab entry for a swap partition:
    my_swap /dev/hdb1 /dev/urandom swap,cipher=aes-cbc-essiv:sha256
This creates an encrypted block device /dev/mapper/my_swap, which can be
referenced in /etc/fstab.

For a filesystem volume:
    my_volume /dev/hda5 /etc/volume_key cipher=aes-cbc-essiv:sha256
The /etc/volume_key file contains a plaintext encryption key.  You can
also specify "none" as the key file name, and the system will ask for
the encryption key during boot.

It is recommended to use LUKS for filesystem volumes:
- Create the encrypted volume using (cryptsetup luksFormat)
- Add the necessary entry to /etc/crypttab
- Set up the volume manually using (cryptsetup luksOpen) or reboot
- Create a filesystem on the encrypted volume
- Set up an /etc/fstab entry
