+@section Running Guix on a Linode
+@cindex linode
+
+Start with a recommended Debian server. Be sure to add your ssh key for
+easy login. We recommend using the default distro as a way to bootstrap
+Guix. This is usually done via @code{ssh-copy-id}.
+
+Power the linode down. In the Linode's Disks/Configurations tab, resize
+the Debian disk to be smaller. 30 GB is recommended.
+
+In the Linode settings, "Add a disk", with the following:
+@itemize @bullet
+@item
+Label: "Guix"
+
+@item
+Filesystem: ext4
+
+@item
+Set it to the remaining size
+@end itemize
+
+On the "configuration" field that comes with the default image, press
+"..." and select "Edit", then on that menu add to /dev/sdc the "Guix"
+label.
+
+Now "Add a Configuration", with the following:
+@itemize @bullet
+@item
+Label: Guix
+
+@item
+VM Mode: Paravirtualization @c{The default?? Does this matter?}
+
+@item
+Kernel: Grub 2 (it's at the bottom! This step is @b{IMPORTANT!})
+
+@item
+Block device assignment:
+
+@item
+/dev/sda: Guix
+
+@item
+/dev/sdb: swap
+
+@item
+Root device: /dev/sda
+
+@item
+Turn off all the filesystem/boot helpers
+@end itemize
+
+Now power it back up, picking the Debian configuration. Once it's
+booted up, ssh in your server via @code{ssh root@@<your-server-ip-here>}.
+Now you can run the "install guix form binary installer" steps:
+
+@example
+sudo apt-get install gpg
+wget https://sv.gnu.org/people/viewgpg.php?user_id=15145 -qO - | gpg --import -
+wget https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh
+chmod +x guix-install.sh
+./guix-install.sh
+guix pull
+@end example
+
+Now it's time to write out a config for the server. The key information
+is below. Save the resulting file as guix-config.scm:
+
+@lisp
+(use-modules (gnu)
+ (guix modules))
+(use-service-modules networking
+ ssh)
+(use-package-modules admin
+ certs
+ package-management
+ ssh
+ tls)
+
+(operating-system
+ (host-name "my-server")
+ (timezone "America/New_York")
+ (locale "en_US.UTF-8")
+ ;; This goofy code will generate the grub.cfg
+ ;; without installing the grub bootloader on disk.
+ (bootloader (bootloader-configuration
+ (bootloader
+ (bootloader
+ (inherit grub-bootloader)
+ (installer #~(const #t))))))
+ (file-systems (cons (file-system
+ (device "/dev/sda")
+ (mount-point "/")

+ %base-file-systems))

+ (initrd-modules (cons "virtio_scsi" ; Needed to find the disk
+ %base-initrd-modules))
+
+ (users (cons (user-account
+ (name "janedoe")
+ (group "users")
+ ;; Adding the account to the "wheel" group
+ ;; makes it a sudoer.
+ (supplementary-groups '("wheel"))
+ (home-directory "/home/janedoe"))
+ %base-user-accounts))
+
+ (packages (cons* nss-certs ;for HTTPS access
+ openssh-sans-x

+ (services (cons*
+ (service dhcp-client-service-type)

+ (password-authentication? #f)
+ (authorized-keys
+ `(("janedoe" ,(local-file "janedoe_rsa.pub"))
+ ;; Is this a good idea? Well if you don't add it
+ ;; you have to manually set your user's password
+ ;; via the glish console...
+ ("root" ,(local-file "janedoe_rsa.pub"))))))
+ %base-services)))
+@end lisp
+
+Replace the following fields in the above configuration:
+@lisp
+(host-name "my-server") ; replace with your server name
+(name "janedoe") ; replace with your username
+("janedoe" ,(local-file "janedoe_rsa.pub")) ; here too
+@end lisp
+
+Note the same above for root, which I don't feel great about, but
+otherwise you'll need to log in via the linode "glish" console to log in
+as root and set the user's initial password before you can start using
+sudo. @comment {(is there another way around this?)}
+
+Save your ssh public key (@code{~/.ssh/id_rsa.pub}) as
+<your-username-here>_rsa.pub in the same directory.
+
+Mount the guix drive:
+@example
+mkdir /mnt/guix
+mount /dev/sdc /mnt/guix
+@end example
+
+Due to the way we set things up above, we do not install Grub
+completely. Instead we install only our grub configuration file. So we
+need to copy over some of the other Grub stuff that is already there:
+
+@example
+mkdir -p /mnt/guix/boot/grub
+cp -r /boot/grub/* /mnt/guix/boot/grub/
+@end example
+
+Now initialize the Guix installation:
+@example
+guix system init guix-config.scm /mnt/guix
+@end example
+
+Ok, power it down!
+Now from the linode console, select boot and select "Guix".
+
+Once it boots, you should be able to log in via ssh! (The server
+config will have changed though.)
+
+Be sure to set your password and root's password.
+
+Horray! At this point you can shut down the server, delete the
+Debian disk, and resize the Guix to the rest of the size.
+Congratulations!
+
+BTW, if you save it as a disk image right at this point, you'll have an
+easy time spinning up new Guix images!
