'GRUB_CMDLINE_LINUX'
     Command-line arguments to add to menu entries for the Linux kernel.

'GRUB_CMDLINE_LINUX_DEFAULT'
     Unless 'GRUB_DISABLE_RECOVERY' is set to 'true', two menu entries
     will be generated for each Linux kernel: one default entry and one
     entry for recovery mode.  This option lists command-line arguments
     to add only to the default menu entry, after those listed in
     'GRUB_CMDLINE_LINUX'.
