Rhea-2009:1318: Fcoe-Utils; Rhea-2009:1320: Fuse - Red Hat ENTERPRISE LINUX 5.4 - TECHNICAL NOTES Manual

Chapter 2. New Packages
Etherboot provides the capability to boot guest virtual machines using the Preboot eXecution
Environment (PXE). This process occurs before the operating system is loaded; in most cases, the
operating system has no knowledge that it was booted through PXE. Many network adapters contain a
socket where a ROM chip can be installed; this ROM chip is used to store PXE-boot code provided by
Etherboot. At present, Etherboot is only supported for use in KVM.
This version of Etherboot was compiled with the POWERSAVE, PXE_DHCP_STRICT, and
ASK_BOOT=-1 options. PXE_DHCP_STRICT is required by some network drivers to support PXE-
booting, while the ASK_BOOT=-1 option prevents a guest from consuming too much CPU time during
boot-up. The POWERSAVE option reduces CPU consumption on a host whenever a guest performs a
PXE-boot. (BZ#481914

2.5. RHEA-2009:1318: fcoe-utils

A new fcoe-utils package is now available for Red Hat Enterprise Linux 5.
The fcoe-utils package contains the fcoeadm command line utility, which is the Fibre Channel-over-
Ethernet (FCoE) management tool for Linux systems. The fcoeadm utility can create, destroy and
reset an FCoE instance on a given network interface, as well as retrieve and display information about
FCoE instances.
This fcoe-utils package is new to Red Hat Enterprise Linux 5.
All Fibre Channel-over-Ethernet users requiring an administrative FCoE interface should install this
newly-released package, which adds this enhancement.

2.6. RHEA-2009:1320: fuse

fuse, a new package that enables users to mount FUSE file systems, is now available.
FUSE (Filesystem in Userspace) is an interface for userspace programs to export a virtual file system
to the Linux kernel. FUSE also aims to provide a secure method for non-privileged users to create and
mount their own file system implementations.
FUSE, which can implement a fully functional file system in a userspace program, consists of three
main parts: a kernel filesystem module; a userspace library; and a mount utility. This package contains
the mount utility, fusermount; the FUSE userspace tool to mount FUSE file systems.
Note
FUSE has no relationship with the ZX Spectrum emulator also known as Fuse.
Anyone looking to mount FUSE file systems or otherwise use FUSE should install this new package.
