Details:

Some Linux distros (example: ntpasswd) utilize multiple initrd cgz images when
booting.  grub-legacy added support for this feature so booting was possible
with:

initrd /ntpasswd/initrd.cgz
initrd /ntpasswd/scsi.cgz

Grub would write in the contents of initrd.cgz into memory and then add on the
contents of scsi.cgz (overwritting any paths with the same name with the
second cgz).

This allowed the distro to boot and load additional files,drivers,etc.

grub2 doesn't seem to support these options.


A work around is to extract the contents of the cgz and combine them into a
single one.  However when booting various isos from a usb key it is nice to
not have to manually create this single image.
