.Adding a new entry with additionnal kernel arguments
To add a new entry with the default kernel but with additionnal kernel arguments and make it the default entry, use:
[subs="macros"]
----
~]# grubby --add-kernel $(grubby --default-kernel) --copy-default --args=crashkernel=128M --title "Default kernel with kdump support" --make-default
