Hi, This patch allow passing command line options to core.img or g2ldr:
For example, in grub2:
multiboot /core.img prefix=(hd0,1)/boot/grub
multiboot /core.img root=(hd0,1)
linux /g2ldr prefix=(hd0,1)/boot/grub
linux /g2ldr root=(hd0,1)
prefix will take preference over root.
you can also set other variables, for example:
multiboot /core.img root=(hd0,1) debug=all
This patch also set the boot device in the multiboot loader, for example:
set root=(hd0,1)
multiboot /core.img
boot
It will show the menu instead of rescue mode.
