5.18. less
The less utility is a text file browser that resembles more, but with more capabilities ("less is more").
The less utility allows users to move backwards in the file as well as forwards. Because less need not
read the entire input file before it starts, less starts up more quickly than text editors (vi, for example).
• The "less" command has been updated. less no longer adds the "carriage return" character when
wrapping long lines. Consequently, lines longer than the terminal width will be displayed incorrectly
when browsing the file line per line. The command line option "--old-bot" forces less to behave as it
did previously, with long text lines displayed correctly.

5.19. libcmpiutil
libcmpiutil is a library of utility functions for CMPI providers. Its goal is to reduce the amount of
repetitive work done in most CMPI providers by encapsulating common procedures with more
"normal" APIs. This includes operations such as retrieving typed instance properties, standardizing
method dispatch and argument checking.
• The libcmpiutil-devel package depends on tog-pegasus-devel, which for the Red Hat Enterprise
Linux Desktop product is only available from the Workstation option. Therefore, any attempt to
install the libcmpiutil-devel package on a system that does not have a Subscription including
the Workstation option or is not subscribed to the Workstation channel on RHN, will fail with an
unresolved dependency error.
5.20. libvirt
Problem Description: The libvirt library is a C API for managing and interacting with the virtualization
capabilities of Linux and other operating systems. In addition, libvirt provides tools for remotely
managing virtualized systems.
• Volumes created using the libvirt storage API may not have an SELinux label that allows access
by virtual machines. If an SELinux AVC denial is reported when starting a Xen or KVM guest, the
adminstrator should either manually relabel the file/device, or add the file path(s) as rule to the
SELinux policy using the 'semanage' tool.

5.21. lvm2
The lvm2 package contains support for Logical Volume Management (LVM).
The following are the Known Issues that apply to the lvm2 packages in Red Hat Enterprise Linux 5.4
• The
lvchange
command is used to change the attributes of a logical volume. Issuing the
lvchange
command on a volume group that contains a mirror or snapshot may result in messages
similar to the following:
Unable to change mirror log LV fail_secondary_mlog directly
Unable to change mirror image LV fail_secondary_mimage_0 directly
Unable to change mirror image LV fail_secondary_mimage_1 directly
These messages can be safely ignored.
