It’s building!

Hello Guix!

Good news: the new machine, bayfront.guixsd.org, is building Guix master
for x86_64/i686 with Cuirass⁰!

You can get substitutes from https://bayfront.guixsd.org; just authorize
its key (with ‘guix archive --authorize’), which is:

  (public-key 
   (ecc 
    (curve Ed25519)
    (q #8D156F295D24B0D9A86FA5741A840FF2D24F60F7B6C4134814AD55625971B394#)))

The machine was initially installed using substitutes from
hydra.gnu.org, but ever since it has been building stuff on its own (it
does not offload to any other machine at this point).  Thus it can be
used to check for reproducibility issues:

  guix challenge gdk-pixbuf \
    --substitute-urls="https://mirror.hydra.gnu.org https://bayfront.guixsd.org"

The machine runs GuixSD and its config is under version control:

  http://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/bayfront.scm

Currently Cuirass doesn’t expose much over HTTP¹ but hopefully we can
incrementally add the URLs that guix-hydra.el expects.

There are a few glitches to address, such as the fact that it builds
with max-jobs = 1 due to <https://bugs.gnu.org/20217>, but we’ll get
there.

Woohoo!  :-)

As mentioned in another thread, this is now summarized here:

  https://www.gnu.org/software/guix/packages/reproducibility.html

The code for this page uses the API of ‘guix challenge’:

  http://git.savannah.gnu.org/cgit/guix/guix-artwork.git/tree/website/www/packages.scm#n467

Although for many packages we can’t tell anything because bayfront
hasn’t built them yet, we can already see that a number of packages have
reproducibility issues, some of which were already filed at
<https://bugs.gnu.org/>.

Let’s address these!

To investigate reproducibility issues, you need to extract the nars
linked from the page above with ‘guix archive -x’, as shown at:

  https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-challenge.html

(Remember that those from hydra.gnu.org are bzip2-compressed, while
those from bayfront are gzipped.)

Hi Ludo, I have a couple questions. I autorized bayfront like so ...

g1@g1 ~/src$ cat bayfront.guixsd.org.pub
 (public-key 
  (ecc 
   (curve Ed25519)
   (q #8D156F295D24B0D9A86FA5741A840FF2D24F60F7B6C4134814AD55625971B394#)))

g1@g1 ~/src$ sudo guix archive --authorize < bayfront.guixsd.org.pub

... and I read this ...

3.7 Invoking ‘guix archive’
===========================
[...]
     The list of authorized keys is kept in the human-editable file
     ‘/etc/guix/acl’.  The file contains “advanced-format s-expressions”
     (http://people.csail.mit.edu/rivest/Sexp.txt) and is structured as
     an access-control list in the Simple Public-Key Infrastructure
     (SPKI) (http://theworld.com/~cme/spki.txt).

... so I expected to find the bayfront key here ...

Could it be that the ‘guix archive’ you ran uses a configuration
directory other than this one?  What does:

  guile -c '(use-modules (guix config)) (pk %config-directory)'

print?

Yes.  It is not actually importing the archives into your store, only
looking at the content hashes that the servers advertise, so there is no
risk here and no requirement to authenticate.

That said, we could add an option to restrict to authorized servers.

HTH!

Hmm so that should definitely be writing to /etc/guix/acl.  Maybe you
could strace it to see what’s happening?

I remember being equally confused by not finding the key imported in the
/etc/guix/acl file, as per the manual.

On my GuixSD system, the value of %config-directory is:
"/usr/local/etc/guix", and the file "/usr/local/etc/guix/acl" does
contain multiple times the public key of Bayfront, which must be due
to passed attempts at adding the Bayfront key using "guix archive".

I suppose that’s because you installed Guix in /usr/local at some point?

myglc2, are you in a similar situation?

Hmm, apparently so ...

guile -c '(use-modules (guix config)) (pk %config-directory)'

... returns ...

;;; ("/etc/guix")

... but in the REPL I get ...

(use-modules (guix config))
(pk %config-directory)

=> "/usr/local/etc/guix"

... /usr/local/etc/guix/acl is the only file under /usr and I didn't
install in /usr/local.  The system was created with 'guix init' on a
previous GuixSD system and has since been modified by 'guix reconfigure'
and 'guix package', running either from 'git pull' or git checkout.

I don't know if this is related, but I see that guix config.log
(attached) has ...

guix_sysconfdir='/usr/local/etc'

Also, you may recall that, on the previous system, we had to make
/usr/local/sbin/guix-register a symlink to guix-register to get 'guix
init' to work ...

Right.

‘guix pull’ preserves your (guix config) module.  So if the ‘guix’ you
run was configured to use /etc, it’ll keep using that; if it was
configured to use /usr/local/etc, it’ll keep using that.

If you run “./pre-inst-env guix pull”, then you end up using (guix
config) from your build tree, which is configured to use /usr/local/etc
by default.  That’s probably what happened, no?

To fix it, you can either run:

  rm -f ~/.config/guix/latest && guix pull

or just do:

  ./configure --sysconfdir=/etc

in your checkout.

Admittedly all this is kind of ugly and I look forward to the ‘guix
pull’ replacement…

HTH!

Hi Ludo,

I tried both approaches but ...

sudo guix archive --authorize < bayfront.guixsd.org.pub

... continues to add the key to /usr/local/etc/guix/acl

:-(

Like Maxim, I usually run from the git checkout with
/home/g1/.config/guix/latest pointing to the checkout.

But after ...

rm -f ~/.config/guix/latest && guix pull

... I confirmed ...

stat ~/.config/guix/latest | grep File
  File: '/home/g1/.config/guix/latest' ->
  '/gnu/store/8ag16yziir9gl7rq02vswr31ip4k33ab-guix-latest'

I have attached the config log again in hopes it might provide
insight. I can also provide shell logs if they are of interest.


Also, FWIW, when I did ...

g1@g1 ~/src/guix [env]$ ./configure --sysconfdir=/etc

... it gave this message ...

[...]
checking the current installation's localstatedir... /var
configure: error: chosen localstatedir '/usr/local/var' does not match that of the existing installation '/var'
Installing may corrupt /gnu/store!
Use './configure --localstatedir=/var'.

... which left me wondering if it meant ...

1) it failed, or

2) it worked, but results would be unpredictable

So maybe this message should be made more clear.

Do like it says.  :-)

That is, it noticed that your system has /var/guix/db and that you were
configuring with a different state directory, which is a mistake you’d
rather avoid (see the bits about localstatedir at
<https://www.gnu.org/software/guix/manual/html_node/Requirements.html>).

So:

  ./configure --localstatedir=/var --sysconfdir=/etc -C

I ran guix pull initially (before starting to use a git checkout). And
I remember mistakenly running "guix pull" from my guix checkout, which
if I followed your explanation would have caused (guix config) to point
to /usr/local/etc. So that seems like a plausible explication! I guess
in the newer Guix releases the default path has been fixed (to /etc)?

I ran ./configure --localstatedir=/var --sysconfig=/etc && make, and I
can now confirm that it fixed it:

guile -c "(use-modules (guix config)) (pk %config-directory)"
;;; ("/etc/guix")

I also checked that:

sudo guix archive --authorize < bayfront.guixsd.org.pub

Produced an entry in /etc/guix/acl.

George, as an alternative, you might be interested in declaring the extra
key in your system's config.scm file [0].

Thanks for the help, Ludovic!

Could you please clarify? Does it do this when invoked by 'guix pull' or
by './pre-inst-env guix pull', or in both cases?

I don't use './pre-inst-env' so I don't think so. But maybe I did on the
system from which I did 'system init' to create this one. Would that
explain it?

Great point, thank you Maxim.

Not that I'm aware of. Like myglc2, I installed GuixSD from the USB
bootable image, following the manual instructions (guix system init or
similar).

It seems that both myglc2 and I are running guix from a git
checkout. Could this has something to do with it?

Thanks,

Maxim

If anyone else would like to use the new bayfront substitute server by
declaring it in their config.scm you can consult the config I'm using
below, which is based on the lightweight desktop config base.

The important bits added are (guix-store) and (gnu services base) in the
topmost (use-modules ...) sexp, as well as in the modified (services ...) one.

Thanks for those who offered guidance on how to do this in the #guix irc
channel!

I think when you only use desktop-services, it works.

Identation broken because this happens when you copy from emacs
with X into terminal emacs.

Obviously this fails because "config" is not known.
Just modifying the service the way you did it doesn't work for
me.
I'm open for ideas on how to erase ntp from the services in a
better way, I'm running a replacement for ntpd.

Later this %desktop-services-sans-ntpd gets used in (services).

This isn’t going to work because you ripped this chunk from a
“modify-services” expression.

> Identation broken because this happens when you copy from emacs

You can use C-M-q to reindent an expression.

> Obviously this fails because "config" is not known.

That’s because you’re not doing this within “modify-services”.

> I'm open for ideas on how to erase ntp from the services in a
> better way, I'm running a replacement for ntpd.

You can use regular Scheme to filter lists, for example:

    (filter (compose not (cut eq? 'ntp <>) service-type-name service-kind) %desktop-services)

This means: run through all elements of “%desktop-services”, extract the
service type (“service-kind”), extract the type name from the kind (“service-type-name”), check if it’s equal
to 'ntp (“(cut eq? 'ntp <>)”), then throw it out (“not”).  The first
argument to “filter” is just a big function.
