RHBA-2013:1713 - grubby bug fix update

Synopsis

grubby bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

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

Description

The grubby packages provide grubby, a command-line tool for displaying and editing GRUB (GRand Unified Bootloader) configuration files.

This update fixes the following bugs:

  • Previously, the grub.conf file was not properly updated after a kernel update with the tboot bootloader. This was due to a bug in the grubby tool which caused it to improperly interpret the grub.conf stanzas that had tboot in them. This update enables grubby to read the HYPERVISOR and HYPERVISOR_ARGS parameters from the /etc/sysconfig/kernel file in order for tboot to perform as intended. (BZ#991197)

  • Prior to this update, yum and anaconda upgrades could have failed with a kernel panic on the AMD64 and Intel 64 architectures due to the RAM disk image not being found. This only happened when tboot was installed, and the kernel "%post" or "%posttrans" scripts were run. This update adds the initramfs disk image to the grub entry, and kernel panic failures no longer occur in the described scenario. (BZ#999908)

Users of grubby are advised to upgrade to these updated packages, which fix these bugs.

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 https://access.redhat.com/site/articles/11258
