Re: [RFC] Allow separate boot block and core.img location?

sda1 was just an example taken from the original request:
grub-install --boot-block-location=/dev/sda1 --core-img-location=/dev/sda 
The intent there was to install the boot block (boot.img) into the first sector of sda1, which is what my suggested workaround would have done as well.
Also, if sda1 happens to be a fat or ntfs volume, this would need to be tweaked to ensure that the critical volume parameters are preserved.
The assumption in both cases is that the user knows what they are doing...

Cheers!

sda1 might not like having it's first sector overwritten.
