-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.
