grub2 miscelanea questions #2

[adrian15]

1) search command file not found:
=====================================
        If you search for an inexistant file like:
        search -f /boot/grub/und-video
        it complains:
        error: no such device

        Shouldn't it be:
        error: no such file /boot/grub/und-video

I mean it has to talk about files not devices and it has also to prompt
the file you have searched for... or maybe not, I do not know.

I ask marco_g if I am going to be able to use this command inside an if
statement.

        if `search -f /boot/grub/grub2.cfg` then

2) chainload a device
========================

It seems that if I run:
        chainloader (hd0)+1
        boot
It boots my hard disk installed bootloader.

However chainloader help only prompts:
        chainloader [-f] FILE
I think the help should be:
        chainloader [-f] FILE|DEVICE

3) DEVICE vs DEVICENAME
========================

If you check the loopback command help you will see that you can use a
DEVICENAME as an argument. Should we choose DEVICE or DEVICENAME when
talking about a DEVICE ?


4) About linux command
========================

I do not like the linux command too much. What happens with bsd and
other kernels that are not multiboot?

why don't we have something as:

kernel --type linux whatever
kernel --type bsd whateverelse

?


Or maybe is better to have a bsd command or bsd will become at last a
multiboot os?


5) windows command
=======================
Can we add a windows command that does:
chainloader (hd0,0)+1
boot

A question for marco_g... which it is the best way so that a command can
call other commands?

Using grub_cmd_name where name is the name of the command or can I write
a grub.cfg file on the fly and then send it to some cfg interpreter
function?


6) boot command boots also boot loaders
=====================================
If we can use chainloader for preparing to boot another boot loader...
then boot help should read:

Boot an operating system or another boot loader.

instead of:

Boot an operating system.
