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
