RHBA-2012:0386 - Bug Fix Advisory

Topic

An updated yum package that fixes one bug is now available for Red Hat
Enterprise Linux 6.

Description

Yum is a command line utility that allows the user to check for updates and
automatically download and install updated RPM packages. Yum automatically
obtains and downloads dependencies, prompting the user for permission as
necessary.

This update fixes the following bug:

• The anacron scheduler starts the yum-cron utility with the "nice" value of 10.

This caused Yum's RPM transactions to run at very low priority level. Also, any
updated service inherited this "nice" value, which influenced the system
behavior. This update adds the "reset_nice" configuration option, which allows
Yum to reset the "nice" value to 0 before running an RPM transaction. With this
option set, Yum's RPM transactions run at normal priority level so that updated
services are restarted with normal priority as expected. (BZ#795455)

All users of yum are advised to upgrade to this updated package, which fixes
this bug.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
