bug#30370: guix system init can't find guix-register

[Diego Nicola Barbato]

Hello Guix,

I tried to install GuixSD on a loop device (/dev/loop1) whith its main
partition mounted under /mnt like this:

$ guix system init /mnt/etc/config.scm /mnt

This failed with the following error message:

Betriebssystem unter »/mnt« wird initialisiert …
In execvp of /gnu/store/d4wwx93gqizx132zjk7h1ir7rzph0pig-guix-0.12.0-10.ba2260d/sbin/guix-register: Datei oder Verzeichnis nicht gefunden
copying to '/mnt'...
guix system: error: fport_write: Datenübergabe unterbrochen (broken pipe)

I run GuixSD on an x86_64 machine (commit:
a3a932c008d0d9051eb8cdfdcea07ebd7b68b1b3) and the configfile is a copy
of the `bare-bones.tmpl' with the target field in the
bootloader-configuration changed to "/dev/loop1".

Greetings

Diego

I suppose you’re running this in a chroot, right?  How did you populate
that chroot?  Could it be that it misses some store items?

Thanks,

The above line should actually be:
$ sudo guix system init /mnt/etc/config.scm /mnt

I am not running this in a chroot.
I am afraid the explanation of what I was doing was a bit unclear.  I
was able to reproduce the error with the following steps:

$ mkdir test
$ cd test
$ qemu-img create -f raw test.img 7G
$ cfdisk test.img

I selected gpt and wrote two partitions: the first one with a size of 1M
and type BIOS boot, the second with a size of 7G and type Linux
filesystem.

$ sudo losetup --partscan --show --find test.img
/dev/loop1
$ sudo mkfs.ext4 -L my-root /dev/loop1p2
$ sudo mount /dev/loop1p2 /mnt
$ sudo mkdir /mnt/etc
$ sudo sh -c "sed 's#/dev/sdX#/dev/loop1#g' ../.config/guix/latest/gnu/system/examples/bare-bones.tmpl > /mnt/etc/config.scm"
$ sudo guix system init /mnt/etc/config.scm /mnt

It does not matter that it is a loopback device.  The same thing happens
if I try to install it on a USB flash drive.
The issue seems to be that there is no

Could you try to figure out where that
d4wwx93gqizx132zjk7h1ir7rzph0pig-guix-0.12.0-10.ba2260d comes from?

Also, current master is at 0.14.0*, so it’s surprising that you end up
using such an old version.

Could it be that ~root/.config/guix/latest points to that old Guix?
Does “sudo guix pull” help?

Thanks,
Ludo’.

I could not figure out where this comes from.  As I mentioned it is not
in my store, yet (only) "guix system init" seems to look for it.

> Also, current master is at 0.14.0*, so it’s surprising that you end up

It is indeed quite surprising.  Especially since "type -P guix-register"
returns "/run/current-system/profile/sbin/guix-register" which links to
"/gnu/store/b5hfsdq8yzcqfvikfhm0gk95xa5pfwgy-guix-0.14.0-7.33988f9/sbin/guix-register"
and "type -P guix" returns "/run/current-system/profile/bin/guix" which links to
"/gnu/store/b5hfsdq8yzcqfvikfhm0gk95xa5pfwgy-guix-0.14.0-7.33988f9/bin/guix"
(for both my user and root).

> Could it be that ~root/.config/guix/latest points to that old Guix?

It did not (I ran "guix pull" as user and as root last Friday,
2018-02-02).  And now after running "guix pull" again (as both user and
root) ~root/.config/guix/latest and ~/.config/guix/latest point to
/gnu/store/a565qard9xc0f0mg0vlbsrn419qgwfp9-guix-latest.

> Does “sudo guix pull” help?

Unfortunately "sudo guix pull" and "guix pull" did not help either.
The error persists even after running
"guix system reconfigure /etc/config.scm" and rebooting.

I mean, can you run something like:

  grep -r d4wwx93gqizx132zjk7h1ir7rzph0pig \
    $(dirname $(dirname $(readlink -f $(type -P guix))))

?

TIA,

This did not return anything.
But I also tried running
"grep -r d4wwx93gqizx132zjk7h1ir7rzph0pig ~/.config/guix/latest" which
returned this:
/home/diego/.config/guix/latest/guix/config.scm:  "/gnu/store/d4wwx93gqizx132zjk7h1ir7rzph0pig-guix-0.12.0-10.ba2260d/sbin")

Bingo!  This string is inherit from the (guix config) of your initial
installation, the one you used to run ‘guix pull’.

I would call this a ‘guix pull’ bug.

I think this is a bug in the ‘build’ procedure defined in build-self.scm
which is used by guix pull’ and which uses the (guix build pull) module
to generate a new config.scm.  It uses the value for %sbindir defined in
(guix config) which causes it to be passed on unchanged.
My guess is that (find-best-packages-by-name "guix" #f) should be used
to determine the correct guix instead, which is how the values for the
dependencies (libgcrypt, zlib, ...) are determined, and that this should
be used to get the sbin directory with ‘string-append’.
WDYT?
