Dear team at grub-devel,
First of all I would like to thank you for the Grand boot loader, your work is very
much appreciated.
Recently I downloaded the current grub-2.02-beta3 and started experimenting with it.
I am am making use of the luks module in GRUB to provide my clients with fully encrypted
harddrives. Since my clients are German, and I keep telling them that strong passwords
should contain special characters, I ended up modifying the default keyboard layout
for the at_keyboard.c input driver. I provided the diff in keylayouts.c.diff, if you want
to make use of it. The support for German keys is only partial, since some of the German
keys are non-ASCII.
Also I patched at_keyboard.c. It has a minor typo, in line 91 both scancode 0x52 and
0x53 are mapped to the same GRUB_KEYBOARD_KEY_NUMDOT. This is wrong, scancode 0x52
has to be mapped to GRUB_KEYBOARD_KEY_NUM0 (as that's what it is).
Last but not least, parsing through include/grub/keyboard_layouts.h, I realized that the
enumeration of GRUB_KEYBOARD_KEY_* is skipping value 0x31:
> GRUB_KEYBOARD_KEY_RBRACKET = 0x30,
> GRUB_KEYBOARD_KEY_BACKSLASH = 0x32,
I do not know why this is the case, but from my point of view this probably lead to the
following comment ( in grub-core/commands/keylayouts.c ):
> /* According to usage table 0x31 should be mapped to '/'
> but testing with real keyboard shows that 0x32 is remapped to '/'.
> Map 0x31 to 0.
Cleaning up the enumeration would do some good, I guess.
Find attached both aformentioned patches. I'll be glad help out if you deem it appropriate
to, e.g. make the support for German at_keyboard layout a configurable option.
Regards, Frank
