Hi!

I installed GuixSD yesterday and found a bug this morning when trying
to build a new system generation.


Here is the config file I use:

(use-modules (gnu) (gnu system nss))
(use-service-modules networking)
(use-package-modules certs xorg xdisorg fonts admin zsh)

(operating-system
  (host-name "crocmou")
  (timezone "Europe/Paris")
  (locale "en_US.UTF-8")

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

  (initrd (lambda (file-systems . rest)
            (apply base-initrd file-systems
                   #:extra-modules '("sata_nv")
                   rest)))


  (file-systems (cons (file-system
                        (title 'uuid)
                        (device (uuid "a08e57ba-6275-4e22-90e5-1d9b34ae363d"))
                        (mount-point "/")
                        (type "ext4"))
                      %base-file-systems))

  (users (cons (user-account
                (name "kooda")
                (comment "The otter user")
                (group "users")
                (supplementary-groups '("wheel" "netdev"
                                        "audio" "video"))
                (home-directory "/home/kooda")
                (shell #~(string-append #$zsh "/bin/zsh")))
               %base-user-accounts))

  ;; This is where we specify system-wide packages.
  (packages (cons* nss-certs         ;for HTTPS access
                   xorg-server xf86-video-ati xf86-input-evdev
                   xf86-video-vesa
                   ;; rxvt-unicode font-terminus font-dejavu htop
                   %base-packages))

  (setuid-programs (cons* #~(string-append #$xorg-server "/bin/Xorg")
                          %setuid-programs))

  (services (cons* (console-keymap-service "fr-bepo")
                   (dhcp-client-service)
                   %base-services)))



Running `guix system build /etc/config.scm` fails with the following error:

Backtrace:

The odd bytevector from the error seems to be the partition’s UUID,
but I get the exact same error when trying to use a label instead of
the UUID.

I found that this same bytevector is what the current generation
refers to as root device:

  kernel: /gnu/store/alqjsslhc7rh1lskxg2xjh6cs37ms1kd-linux-libre-4.6.3



I also ran `guix pull` this morning so I have a recent version.

I cannot reproduce it with current master.

Yes.

Unless I’m mistaken, the problem you report was fixed in
f453f637d5410f4d1e0b3787caa8d34b9b72d7d8 in January.

Could it be that you run ‘guix pull’ as a user but not as root?
Remember that ‘guix pull’ is per-user.

Thanks,
Ludo’.

Fixed by commit c52bf877e9352cd9f29afb13fd4f7d39ed38f1a0.  I'm closing
this bug, but please re-open it if you believe there's still a problem.

> I cannot reproduce it with current master.

It only happens when one of the *previous* system generations specified
the root fs by UUID.  I guess this was not the case in your tests.

It turns out there was another place that needed fixing:
'previous-grub-entries' in (guix scripts system).  When the root device
of an older generation is specified by UUID, the root device stored in
${system}/parameters is a bytevector, and 'boot-parameters-root-device'
returns a bytevector.  'system->grub-entry' passes this bytevector to
'string-append' and that's what's happening in the backtrace above.

Ooh I see, thanks for digging into it!
