When it comes to installing Guix System for the first time on a new machine,
you can basically proceed in three different ways. The first one is to use
an existing operating system on the machine to run the
init command (see Invoking
guix system). The second one, is to produce
an installation image (see Construcción de la imagen de instalación). This is a
bootable system which role is to eventually run
guix system init.
Finally, the third option would be to produce an image that is a direct
instantiation of the system you wish to run. That image can then be copied
on a bootable device such as an USB drive or a memory card. The target
machine would then directly boot from it, without any kind of installation
guix system image command is able to turn an operating system
definition into a bootable image. This command supports different image
types, such as
docker. Any modern
x86_64 machine will probably be able to boot from an
image. However, there are a few machines out there that require specific
image types. Those machines, in general using
ARM processors, may
expect specific partitions at specific offsets.
This chapter explains how to define customized system images and how to turn them into actual bootable images.
