Instalação em um pendrive e em DVD (Manual de referência do GNU Guix)

3.3 Instalação em um pendrive e em DVD

An ISO-9660 installation image that can be written to a USB stick or burnt to a DVD can be downloaded from ‘https://ftp.gnu.org/gnu/guix/guix-system-install-1.4.0.x86_64-linux.iso’, where you can replace x86_64-linux with one of:

x86_64-linux: for a GNU/Linux system on Intel/AMD-compatible 64-bit CPUs;
i686-linux: for a 32-bit GNU/Linux system on Intel-compatible CPUs.

Make sure to download the associated .sig file and to verify the authenticity of the image against it, along these lines:

$ wget https://ftp.gnu.org/gnu/guix/guix-system-install-1.4.0.x86_64-linux.iso.sig
$ gpg --verify guix-system-install-1.4.0.x86_64-linux.iso.sig

Se esse comando falhar porque você não possui a chave pública requerida, execute este comando para importá-lo:

$ wget https://sv.gnu.org/people/viewgpg.php?user_id=15145 \
      -qO - | gpg --import -

e execute novamente o comando gpg --verify.

Take note that a warning like “This key is not certified with a trusted signature!” is normal.

This image contains the tools necessary for an installation. It is meant to be copied as is to a large-enough USB stick or DVD.

Copying to a USB Stick
Burning on a DVD
Booting

Copying to a USB Stick

Insert a USB stick of 1 GiB or more into your machine, and determine its device name. Assuming that the USB stick is known as /dev/sdX, copy the image with:

dd if=guix-system-install-1.4.0.x86_64-linux.iso of=/dev/sdX status=progress
sync

Access to /dev/sdX usually requires root privileges.

Burning on a DVD

Insert a blank DVD into your machine, and determine its device name. Assuming that the DVD drive is known as /dev/srX, copy the image with:

growisofs -dvd-compat -Z /dev/srX=guix-system-install-1.4.0.x86_64-linux.iso

Access to /dev/srX usually requires root privileges.

Booting

Once this is done, you should be able to reboot the system and boot from the USB stick or DVD. The latter usually requires you to get in the BIOS or UEFI boot menu, where you can choose to boot from the USB stick. In order to boot from Libreboot, switch to the command mode by pressing the c key and type search_grub usb.
