I’m using a separate encrypted /home and a swap partition, so the
declaration looks like this:

--8<---------------cut here---------------start------------->8---
(operating-system
  (host-name "pluto")
  (timezone "Europe/Paris")
  (locale "en_US.utf8")

  (bootloader (grub-configuration
               (device "/dev/sda")))

  (mapped-devices (list (mapped-device
                         (source "/dev/sda3")
                         (target "home")
                         (type luks-device-mapping))))

  (file-systems (cons* (file-system
                         (device "root")
                         (title 'label)
                         (mount-point "/")
                         (type "ext3"))
                       (file-system
                         (device "/dev/mapper/home")
                         (mount-point "/home")
                         (type "ext3"))
                       %base-file-systems))

  (swap-devices '("/dev/sda4"))                   ;XXX: LABEL=swap

  ;; ...
  )
--8<---------------cut here---------------end--------------->8---

Normally you just need to add extra ‘file-system’ declarations for /var
and /boot in there, and you’re done.

/usr doesn’t make sense on GuixSD because that directory is not used at
all.

HTH,
Ludo’.
