RHBA-2011:1448 - Bug Fix Advisory

Topic

Updated udev packages that resolve one bug are now available for Red Hat
Enterprise Linux 5.

Description

The udev packages implement a dynamic device-directory, providing only the
devices present on the system. This dynamic directory runs in user space,
dynamically creates and removes devices, provides consistent naming, and a user
space API. The udev device manager replaces the devfs device file system,
providing greater hot plug functionality.

This update fixes the following bug:

• On a system boot, the udev helper application, pam_console_apply, was called

for every disk that appeared on the system. This was unnecessary for example for
SCSI disks, which do not have set default pam console permissions. As a
consequence, the boot process was significantly slowed down if a system
contained a large number of disks. To fix this problem, the
/etc/udev/rules.d/95-pam-console.rules file has been marked as a configuration
file and it will not be automatically updated with newer udev versions. System
administrators should now comment out the pam_console_apply call in this file on
systems that do not need a normal console user access to devices. (BZ#736475)

All users of udev are advised to upgrade to these updated packages, which fix
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
