Subject: [PATCH] bootloader: fixed cmdline duplication with BLS and
grub2-mkconfig
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
After application of this patch in order to get rid of the duplicated
kernel command line options (which was duplicated due to the usage of
the grub2-mkconfig), the grub2-mkconfig needs to be run again.
We do not run it automatically in the spec file %post not to break
users not using grub2-mkconfig.
This fix expects that user has not modified the line containing the
GRUB_CMDLINE_LINUX_DEFAULT option and the $tuned_params in the
/etc/default/grub file. If user modified this line, the option
duplication may still occure. In such case, please remove the
$tuned_params from the /etc/default/grub by hand.
