By default all file system modules are added to the GRUB coreboot
payload `default_payload.elf`. This makes the image quite big,
especially as often not all modules are needed.
Introduce the variable `FS_PAYLOAD_MODULES`, which can be used to
explicitly set file systems modules to be added.
$ make default_payload.elf
test -f default_payload.elf && rm default_payload.elf || true

So, the resulting payload size is around 370 kB smaller. (Adding it to
the CBFS, it will be compressed, so the effective size difference will
be smaller.)

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
