The --boot-directory argument is optional; if you don't specify it, grub-install uses /boot.
The grub-install(8) manual page says:
--boot-directory=DIR install GRUB images under the directory DIR/grub instead of the /boot/grub directory
The change in behaviour is that when you use --boot-directory to point to the root/mount point of a device X, it used to write to X/boot/grub not X/grub. NBD now that I know, but it is a change from the current Ubuntu's grub2 version and therefore from many of the howto/blog examples out there on the interwebs.
I'll follow up with the authors of that script to let them know grub2's changed its MBR code with 1.99.
OT - Do you (or anyone) know of a tool (other than boot-info-script) that parses all block device bootloaders and reports what type they are and where they're pointing to?
You could have used chroot and then run grub-install without specifying --boot-directory if you wanted.
this is Linux. There are choices. Comamnds have options to cater for a wide variety of needs and preferences. You don't have to use this option if you don't want to. It's documented precisely in the manual page.
Thanks for the clarification.
