RHBA-2012:0331 - dracut bug fix update

Synopsis

dracut bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated dracut packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

The dracut packages include an event-driven initramfs generator infrastructure based on the udev device manager. The virtual file system, initramfs, is loaded together with the kernel at boot time and initializes the system, so it can read and boot from the root partition.

This update fixes the following bug:

  • When sourcing dracut modules, dracut did not check whether the "install" script for the module exists and is executable. Therefore, if the script was missing, an attempt to execute the script failed. As a consequence, dracut did not execute the "installkernel" script, and the module was not included in the initramfs image. This problem has been fixed, dracut now performs the check and only executes the "install" script when it exists. Then, the "installkernel" script is correctly executed and the module is installed in the initramfs image. (BZ#790943)

  • Previously, dracut did not correctly handle a situation when booting a system with a degraded RAID array. In such a case, the initial RAM disk image (initramfs) was not able to start the array and the system did not boot. With this update, the initramfs forces the array to start and the system now boots as expected. (BZ#791128)

All users of dracut are advised to upgrade to these updated packages, which fix these bugs.

Solution

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