mount -t ecryptfs /mnt/secret /mnt/secret
The secured portion of the file system should not be exposed, i.e. it should not be mounted to
other mount points, bind mounts, and the like.
• eCryptfs mounts on networked file systems (e.g. NFS, Samba) will not work properly.
• This version of the eCryptfs kernel driver requires updated userspace, which is provided by
ecryptfs-utils-56-4.el5 or newer.
For more information about eCryptfs, refer to http://ecryptfs.sf.net. You can also refer to http://
ecryptfs.sourceforge.net/README and http://ecryptfs.sourceforge.net/ecryptfs-faq.html for basic
setup information.
Stateless Linux
Stateless Linux is a new way of thinking about how a system should be run and managed,
designed to simplify provisioning and management of large numbers of systems by making them
easily replaceable. This is accomplished primarily by establishing prepared system images which
get replicated and managed across a large number of stateless systems, running the operating
system in a read-only manner (refer to /etc/sysconfig/readonly-root for more details).
In its current state of development, the Stateless features are subsets of the intended goals. As
such, the capability remains as Technology Preview.
Red Hat recommends that those interested in testing stateless code read the HOWTO at http://

The enabling infrastructure pieces for Stateless Linux were originally introduced in Red Hat
Enterprise Linux 5.
AIGLX
AIGLX is a Technology Preview feature of the otherwise fully supported X server. It aims to enable
GL-accelerated effects on a standard desktop. The project consists of the following:
• A lightly modified X server.
• An updated Mesa package that adds new protocol support.
By installing these components, you can have GL-accelerated effects on your desktop with very
few changes, as well as the ability to enable and disable them at will without replacing your
X server. AIGLX also enables remote GLX applications to take advantage of hardware GLX
acceleration.
FireWire
The firewire-sbp2 module is still included in this update as a Technology Preview. This
module enables connectivity with FireWire storage devices and scanners.
At present, FireWire does not support the following:
• IPv4
• pcilynx host controllers
• multi-LUN storage devices
