Fedora 9 provides basic support for encrypted swap partitions and
non-root file systems. To use it, add entries to
/etc/crypttab and reference the created devices
in /etc/fstab.
New in Fedora 9, the installer Anaconda has support for creating encrypted file systems during installation. For more information on that, refer to the Fedora Installation Guide.
Installing to encrypted volumes, including the root file system, is now supported. There is no configuration tool for adding or removing keys from volumes at a later time, or otherwise doing modification of the encryption. Refer to this feature page for more information:
http://fedoraproject.org/wiki/Releases/FeatureEncryptedFilesystems
For full instructions on using encrypted file systems, refer to the Fedora Encryption and Privacy Guide.
11.1. Ext4 Preview
The new ext4 file system is available in Fedora 9 as a nearly feature complete preview. Testers are encouraged to review the documentation and try implementations of ext4. When finally integrated, users should experience no problems with the new file system, and should find it bigger, better, and faster.
While an ext3 file system can be mounted as ext4, an ext3 to ext4 conversion tool is planned that converts existing ext3 on-disk format to ext4. For more information about this feature:
