More trials with grub

More trials with grub

[James Jarvis]

Conscious that I am not a developer but it is useful to get feedback on 
the project I have outlined progress mad so far with * to indicate 
questions/discussion points.

I have been building a fat grub2 (using the fatglue.py script from rEFIT 
project) to use on Intel Macs (mac mini; iMac 8,1; iMac 9,1 etc). This 
works on both 32 and 64 bits architectures. Because the modules don't 
work as fat files I tend to use a monolithic grub image. (FWIW, the idea 
is to have a utility boot CD to pass out to our field operators.)

* Is there mileage in having the modules (when insertion is attempted to 
not only try to insert <modpath>/name.mod but also <modpath>/name.<arch>.mod

Incidentally I have checked that I can insert the non-fat modules from 
the fat grub2 monolithic image.

I have managed to have it boot from CD but it always chokes when trying 
to find the grub.cfg on the CD - even though I have the required 
filesystems in the monolithic grub image. I see in the README CD support 
is not there yet however if someone has that working, tips would be 
appreciated.

Thanks for a great product,

James

It would be better to use different directories for different modules an
adjust prefix accordingly.

I believe it was caused by a bug in hfs filesystem that I have just
fixed.  With prefix ending with a slash, GRUB would add "/grub.cfg" and
the double slash would confuse hfs.
