File Systems
Fedora 25 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: Releases/FeatureEncryptedFilesystems
For full instructions on using encrypted file systems, refer to the Fedora Encryption and Privacy Guide.
Ext4 Preview
The new ext4 file system is available in Fedora 9 as a nearly feature complete preview. 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.
Fedora 9 may be installed onto an ext4 file system by adding the ext4 option to the installer boot parameters and selecting custom partitioning.
e2fsprogs userspace tools shipping with Fedora 9 are not yet fully ext4-capable. In particular, fsck ability is limited.For more information about this feature:
