I meant especially those to choose the environment (core, basic, full) to boot. I can't see them there.
I don't think we need a menu item for each option. Is this enough (lang is handled always):
- Load full environment (default)
- Load basic environment
- Load core environment
- Enable `Boot in runlevel 3'
- Disable `Boot in runlevel 3' (default)
- Enable `Copy everything to RAM'
- Disable `Copy everything to RAM' (default)
- Enable numlock on boot
- Disable numlock on boot (default)
The rest I don't think is commonly needed. And options like password=<any string> are not possible for me to add with grub2's current menu system.
