RHBA-2011:1171 - Bug Fix Advisory

Topic

An updated setup package that fixes two bugs and adds various enhancements is
now available for Red Hat Enterprise Linux 6.

Description

The setup package contains a set of important system configuration and setup
files, such as passwd, group, and profile.

This update fixes the following bugs:

• Bash provides the PROMPT_COMMAND environment variable containing a command

that is called when a prompt is displayed. Prior to this update, the
PROMPT_COMMAND variable set by a custom profile.d script was overwritten with
the default value from the /etc/bashrc script file. With this update, the
/etc/bashrc script file has been updated so that it now respects a user-defined
PROMPT_COMMAND variable, and does not overwrite it. (BZ#691425)

• Prior to this update, the /etc/host.conf configuration file contained a line

"order host,bind". This line is no longer used by the glibc library and is
therefore redundant. With this update, this line has been removed from the
host.conf file. (BZ#703052)

Additionally, this update adds the following enhancements:

• The retrace-server package creates a user ID (UID) pair and a group ID (GID)

pair, both with the name "retrace" and number "174". This user and group is used
by the Automated Bug Reporting Tool (ABRT) retracing server. Prior to this
update, the aforementioned UID/GID pairs were not reserved by the setup package
so that other packages or system administrators could have accidentally assigned
those values to other users and groups. With this update, the setup package now
reserves these UID and GID names and numbers so that accidental conflicts with
other users and groups do not happen anymore. (BZ#706012)

• The rhev-agent package creates a user ID (UID) pair and a group ID (GID) pair,

both with the name "rhevagent" and number "175". This user and group is used by
RHEV-Agent. Prior to this update, the aforementioned UID/GID pairs were not
reserved by the setup package so that other packages or system administrators
could have accidentally assigned those values to other users and groups. With
this update, the setup package now reserves these UID and GID names and numbers
so that accidental conflicts with other users and groups do not happen anymore.
(BZ#709599)

• The trafficserver package creates a user ID (UID) pair and a group ID (GID)

pair, both with the name "ats" and number "176". This user and group is used for
the configuration management functions over a cluster of nodes. Prior to this
update, the aforementioned UID/GID pairs were not reserved by the setup package
so that other packages or system administrators could have accidentally assigned
those values to other users and groups. With this update, the setup package now
reserves these UID and GID names and numbers so that accidental conflicts with
other users and groups do not happen anymore. (BZ#715266)

All users are advised to upgrade to this updated setup package, which fixes
these bugs and adds these enhancements.
