Hi! Following the example in 6.2.4 Mapped Devices
(mapped-device (source "/dev/sda3") (target "home") (type luks-device-mapping)) I chose not to use the UUID alternative for encrypted root; I'm terrible at memorizing and typing UUIDs. So I used this snippet (full bare-luks.scm below) (mapped-device ;; This does not work (source "/dev/nvme0n1p1") ;; This works (output of cryptsetup luksUUID /dev/nvme0n1p1) ;; (source (uuid "50d96f54-1dbb-48f8-bca5-2f1feb5ff144")) (target "guix") (type luks-device-mapping)) For disk partitioning, I did cryptsetup luksFormat /dev/nvme0n1p1 cryptsetup open --type=luks /dev/nvme0n1p1 guix mkfs.ext4 -L guix /dev/mapper/guix then install, something like mount /dev/mapper/guix /mnt herd start cow-store /mnt guix system init /mnt/root/bare-luks.scm /mnt After booting I get Device /dev/nvme0n1p1 doesn't exist or access denied Using the luksUUID, it works. Except for this hurdle a pleasant and straighforward fresh install :-) Greetings, janneke --8<---------------cut here---------------start------------->8--- ;; lsblk.out ;; NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT ;; sda 8:0 1 14.5G 0 disk ;; ├─sda1 8:1 1 1.4G 0 part ;; └─sda2 8:2 1 40M 0 part ;; nvme0n1 259:0 0 477G 0 disk ;; └─nvme0n1p1 259:1 0 477G 0 part ;; └─guix 253:0 0 477G 0 crypt /mnt --8<---------------cut here---------------end--------------->8--- --8<---------------cut here---------------start------------->8--- ;; bare-luks.scm (use-modules (gnu)) (use-service-modules networking ssh) (use-package-modules screen ssh) (define %supplementary-groups '("wheel" "netdev" "audio" "video" "lp" "kvm")) (operating-system (host-name "dundal") (timezone "Europe/Amsterdam") (locale "en_US.utf8") (bootloader (bootloader-configuration (bootloader grub-bootloader) (target "/dev/nvme0n1"))) (mapped-devices (list (mapped-device ;; This does not work (source "/dev/nvme0n1p1") ;; This works (output of cryptsetup luksUUID /dev/nvme0n1p1) ;; (source (uuid "50d96f54-1dbb-48f8-bca5-2f1feb5ff144")) (target "guix") (type luks-device-mapping)))) (file-systems (cons* (file-system (title 'device) (device "/dev/mapper/guix") (mount-point "/") (type "ext4") (dependencies mapped-devices)) %base-file-systems)) (groups (cons* (user-group (name "janneke")) %base-groups)) (users (cons* (user-account (name "janneke") (group "janneke") (uid 1000) (supplementary-groups %supplementary-groups) (home-directory "/home/janneke")) %base-user-accounts)) (packages (cons* screen openssh wpa-supplicant-minimal %base-packages)) (services (cons* (dhcp-client-service) (console-keymap-service "dvorak" "ctrl") (service openssh-service-type (openssh-configuration (port-number 2222) (permit-root-login #t) (allow-empty-passwords? #f) (password-authentication? #t))) %base-services))) --8<---------------cut here---------------end--------------->8--- -- Jan Nieuwenhuizen <jann...@gnu.org> | GNU LilyPond http://lilypond.org Freelance IT http://JoyofSource.com | Avatar® http://AvatarAcademy.com
