RHBA-2014:1575 - 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
grubby is a command line tool for updating and displaying information about the configuration files for the grub, lilo, elilo (ia64), yaboot (powerpc) and zipl (s390) boot loaders. It is primarily designed to be used from scripts which install new kernels and need to find information about the current boot environment.
This update fixes the following bugs:
-
Prior to this update, the Trusted Boot (tboot) module incorrectly used the tboot.gz multiboot image to search for a grub configuration file. As a consequence, running the "yum update" command led to grubby corrupting the grub.conf file when tboot was enabled and two or more kernels were updated. With this update, tboot uses specific kernel names to search for grub configuration, and corruption of grub.conf no longer occurs in the described scenario. (BZ#1098846)
-
Previously, enabling tboot caused the kernel configuration to not be displayed properly when running the "grubby --info=DEFAULT" command. With this update, multiboot module parameters have been included in the output of "grubby --info", and the configuration displays as expected when tboot is running. (BZ#997934)
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.
