Manual fix of Grub2 impossible

Agree, You "just" have to remeber to chmod +x, update-grub, check grub.cfg
and add what's new to 40_custom. :)

I had a thing with grub1. I like to remove splash and quiet options from the
kernel/linux line. Every time I update kernel, there was always a question
about menu.lst being changed, and what I would like to do about it.

With grub2, I've set GRUB_CMDLINE_LINUX_DEFAULT="" and no more of that.

I also like:
    insmod raid
    insmod mdraid
    insmod ext2
    set root=(md0)

and so on.

That is, I'm feeling fine and hopeful with grub2. Hope it gets closer to
yours and others needs soon. Didn't find any sort mecanism, and for sure no
menu GUI, I agree.

What follows is from



   To prevent a file in */etc/grub.d* from adding items to the menu, remove
   the *executable* bit or remove the applicable file.

   *memtest86+*: If you don't want to have *memtest86+* displayed in your
   menu, run sudo chmod -x /etc/grub.d/20_memtest86+. The file will remain
   but will not be acted upon by *update-grub*.

   *Recovery mode:* If you don't want *Recovery mode* entries for your linux
   kernels, edit */etc/default/grub* and add this line:



   If a custom script in the */etc/grub.d/* folder contains multiple menu
   entries, individual items may be removed and others retained.

   Tip: If the user wants his custom entries to appear at the top of the
   menu, the file can be named a value less than *"10_linux"*, such as *
   "07_custom"*. Check that the *"DEFAULT"* value in
*/etc/default/grub*points to the correct
   *menuentry* after making this change.

   Changes will not take effect on the Grub 2 menu until "update-grub" is
   run to update *grub.cfg*
