I have found the following problems in doing this;

The instructions are missing a step. You I found I had to do
export pkgdatadir=.
before running ./grub-mkstandalone as otherwise it looks for some files in 
the installed version of grub2 rather than the build location.

Your script
search -s root -f /boot/grub/grub.cfg
configfile /boot/grub/grub.cfg
only checks one location, and the grub.cfg file can be in other places 
such as /grub/grub.cfg if there is a separate boot partition, or 
/boot/grub2/grub.cfg for Fedora. For testing it can be set correctly by 
hand but more locations would need to be searched for general use.

It doesn't seem to understand sub-partitions. I can get it to work if 
the boot files are in /dev/xvda but not in /dev/xvda1 .

I have found the following problems in doing this;

The instructions are missing a step. You I found I had to do
export pkgdatadir=3D.
before running ./grub-mkstandalone as otherwise it looks for some files i=
n=20
the installed version of grub2 rather than the build location.

Your script
search -s root -f /boot/grub/grub.cfg
configfile /boot/grub/grub.cfg
only checks one location, and the grub.cfg file can be in other places=20
such as /grub/grub.cfg if there is a separate boot partition, or=20
/boot/grub2/grub.cfg for Fedora. For testing it can be set correctly by=20
hand but more locations would need to be searched for general use.

It doesn't seem to understand sub-partitions. I can get it to work if=20
the boot files are in /dev/xvda but not in /dev/xvda1 .
