RHBA-2011:0524 - setup bug fix and enhancement update

Synopsis

setup bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated setup package that fixes several bugs and adds various enhancements is now available.

Description

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

This updated setup package fixes the following bugs:

  • When logging in to an interactive login shell, the contents of the /etc/profile script are executed in order to set up an initial environment. Messages which should have been displayed to the user upon logging in to the Korn shell (ksh) were suppressed due to an internal test to determine whether the shell is a login shell that relied upon the value of the PS1 environment variable having already been set before /etc/profile was executed. However, this environment variable is set in the Korn shell only after /etc/profile is executed, which led to messages never being displayed to Korn shell users. This update provides an alternative test that does not rely on the PS1 variable being set before /etc/profile execution, with the result that messages are properly displayed to users of the Korn shell upon login. (BZ#616117)

  • Bash provides the environment variable, PROMPT_COMMAND, containing a command that is called when a prompt is displayed. Previously, the PROMPT_COMMAND command used two separate echo commands. Consequently, if a background process returned text, the text might have displayed in the X terminal title rather than the terminal itself. In this updated package, the PROMPT_COMMAND command uses a single printf statement rather than two echo commands, ensuring returned text displays in the shell. (BZ#620408)

  • Scripts in /etc/profile.d/ can contain special characters (eg spaces) in their filenames. Previously, if a script in the /etc/profile.d/ directory used a space in its filename, error messages were returned every time the shell was started. In this update, the script filenames in /etc/profile.d/ are formatted correctly when called, and consequently, run as expected. (BZ#661645)

  • Previously, using a user defined script in /etc/profile.d/ to modify umask settings failed when using an interactive login shell. Consequently, when this issue was encountered, the default umask settings were used. This updated package provides modified startup scripts, ensuring user defined scripts in /etc/profile.d/ set umask settings as instructed. (BZ#661681)

In addition, this updated package provides the following enhancements:

  • The vdsm-reg package creates a user ID (UID) pair and group ID (GID) pair, both with the name "rhevm" and number "109". This user and group are used as a virtualization agent for Red Hat Enterprise Virtualization Manager. Previously, this UID/GID pair were not reserved during setup and other packages or administrators could accidentally assign those values to other users and groups. The setup package now reserves these UID and GID names and numbers. Accidental clashes with other users and groups are therefore avoided. (BZ#652287)

  • The Automated Bug Reporting Tool (abrt) creates a user ID (UID) pair and group ID (GID) pair, both with the name "abrt" and number "173". The automated bug reporting process uses this user and group when it reports bugs. Previously, this UID/GID pair were not reserved during setup and other packages or administrators could accidentally assign those values to other users and groups. The setup package now reserves these UID and GID names and numbers for abrt. Accidental clashes with other users and groups are therefore avoided. (BZ#670231)

Users are advised to upgrade to this updated setup package, which resolves these issues and adds these enhancements.
