The installation image described above was built using the
system command, specifically:
guix system image -t iso9660 gnu/system/install.scm
Have a look at gnu/system/install.scm in the source tree,
and see also Invoking
guix system for more information
about the installation image.
Many ARM boards require a specific variant of the U-Boot bootloader.
If you build a disk image and the bootloader is not available otherwise (on another boot drive etc), it’s advisable to build an image that includes the bootloader, specifically:
guix system image --system=armhf-linux -e '((@ (gnu system install) os-with-u-boot) (@ (gnu system install) installation-os) "A20-OLinuXino-Lime2")'
A20-OLinuXino-Lime2 is the name of the board. If you specify an invalid
board, a list of possible boards will be printed.
