Re: location configuration

Hi

I'm not sure to really get your point.

/etc/grub.d/ and /etc/default are a directory and a file used by 
grub-mkconfig to generate a grub.cfg file which will then be used by 
Grub2 to boot the PC.

Grub2 looks into /boot/grub to find the files, and more particularly 
grub.cfg, to boot the PC.

In those files and directory you will not been able to find any 
indication on where Grub2 has been installed. It goes the other way 
around : Grub2 looks where you have told it, at installation time, to 
look for the files to be used for booting.

At installation time, you use grub-install to both 1) indicate where to 
store the files (--boot-directory) and 2) where to install grub.
Then you use grub-mkconfig to generate the grub.cfg file in the 
directory you have defined at installation time.

At boot time, the PC looks for a valid bootloader as defined in the boot 
devices listed in the boot setup parameters. It is up to you to have the 
PC looks at first where you have installed Grub2, as the PC uses the 
first valid bootloader when it searches down that devices list.

To analyze your configuration you can use the tool boot-repair to 
produce a report which may help you find out where Grub2 sits.

There also exists a script to produce this kind of report, but I have 
lost its name.
