RHBA-2017:0846 - Bug Fix Advisory

Topic

Updated grubby packages that fix one bug are now available for Red Hat Enterprise Linux 7.1 Extended Update Support.

Description

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

This update fixes the following bug:

• Previously, the grubby tool always set the newly added kernel as the default. The new-kernel-pkg tool originally added the debug boot entry and the normal boot entry, respectively. This caused that the debugging arguments were installed into non-debugging boot entries.

With this update, the invocations in new-kernel-pkg have been fixed to install the debug entry and the normal entry, respectively. As a result, grubby now does not automatically set the latest added boot entry as the default entry and the order of boot entries is set to "normal kernel" and "with debugging", respectively. (BZ#1420746)

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