Booty; Brltty - Red Hat ENTERPRISE LINUX 5.5 - TECHNICAL NOTES Manual

1.15. booty

1.15.1. RHBA-2010:0185: bug fix and enhancement update
An updated booty package that fixes a bug and adds an enhancement is now available.
The booty package contains a python library which provides an interface for the creation of boot
loader configuration files and the addition of stanzas to said configuration files. These boot loader
configuration files are used by the anaconda installer.
This updated booty package fixes the following bug:
* early in the installation process, anaconda creates a ramdisk to hold files that it will need to complete
the installation. Previously, when installing the debug kernel for Red Hat Enterprise Linux on IBM
System z, the ramdisk was larger than the default memory address that ZIPL allocated to hold the
ramdisk. Installation would therefore fail. The /etc/zipl.conf file that booty creates for anaconda now
explicitly specifies a suitable address for the ramdisk so that ZIPL does not rely on the insufficient
default address. With enough space to create the ramdisk, installation succeeds.
In addition, this updated package provides the following enhancement:
* previously, there was no way to configure hypervisor parameters during a kickstart installation.
Therefore, these parameters would have to be configured manually after installation. Red Hat
Enterprise Linux now includes a new option for the "bootloader" command in kickstart, "--hvargs",
which sets hypervisor parameters in grub.conf during installation. It is now possible to automate
this part of the installation process. Refer to the Red Hat Enterprise Linux 5 Installation Guide for a
description of the "--hvargs" option.
Users of booty are advised to upgrade to this updated booty package, which resolves this issue and
adds this enhancement.

1.16.1. RHSA-2010:0181: Low security and bug fix update
Updated brltty packages that fix one security issue and several bugs are now available for Red Hat
Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having low security impact. A
Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.
brltty (Braille TTY) is a background process (daemon) which provides access to the Linux console
(when in text mode) for a blind person using a refreshable braille display. It drives the braille display,
and provides complete screen review functionality.
It was discovered that a brltty library had an insecure relative RPATH (runtime library search path)
set in the ELF (Executable and Linking Format) header. A local user able to convince another user
