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.
|
||||

||||
