[SOLVED] The new grub 2.00, how to disable submenu?
The grub-mkconfig tool makes a submenu for differents kernels, but I don't think it's a good idea. I have searched google but find nothing to disable submenu. And the /etc/default/grub file contains nothing to disable submenu.
Solved, the solution is in #6

Re: [SOLVED] The new grub 2.00, how to disable submenu?
reply to #3:
Thanks for your reply. The method for ubuntu doesn't support archlinux.
reply to #5:
These topics discussed grub's submenu, but they didn't give the method to disable it. But they do help me to find a method to disable the submenu. Thank you!
I add an option called GRUB_ENABLE_SUBMENU and set it to false,here is the patches:

Hmm so official Grub2 doesn't support this? It smells like an upstream feature request to me

Let the path grub-a be the source downloaded from gnu, grub-b be the source patched with archlinux_grub_mkconfig_fixes.patch, grub-c be the source after my modification.

No option to disable it. We can only edit the code.
