address@hidden Building the Installation Image for ARM boards
+Many ARM boards require a board-specific bootloader in order to boot.
+If you build an entire disk image and the is not still available otherwise
+(on another available drive etc), it's advisable to build an image that
+includes the bootloader, specifically:
+guix system disk-image --system=armhf-linux -e '((@ (gnu system install) 
os-with-u-boot) (@ (gnu system install) installation-os) "A20-OLinuXino-Lime2")'
address@hidden example
+Or if you don't cross compile:
+guix system disk-image -e '((@ (gnu system install) os-with-u-boot) (@ (gnu 
system install) installation-os) "A20-OLinuXino-Lime2")'
address@hidden example
+"A20-OLinuXino-Lime2" is the name of the board.  If you specify an invalid
+board, you get a list.
