guix daemon writes acl to /etc/nix/acl not /etc/guix
(address . bug-guix@gnu.org)

On NixOS when I follow the binary installation instructions as of 0.9.0,
it places the acl in the wrong place.

guix archive --authorize < hydra.gnu.org.pub

This puts the file in /etc/nix/acl, not /etc/guix acl. This means the
guix daemon can't find the acl, and you build everything from scratch.

I solved this locally by making them a symlink.

Also, /gnu/store is set to only have 1770 permissions instead of 1774,
which means you can't use any of your guix symlinks with 0.9.0 :/

(guix pki) has:

Toggle snippet (4 lines)
(define %acl-file
(string-append %config-directory "/acl"))

where (guix config) does:

Toggle snippet (5 lines)
(define %config-directory
;; This must match `NIX_CONF_DIR' as defined in `daemon.am'.
(or (getenv "NIX_CONF_DIR") "@guix_sysconfdir@/guix"))

So most likely the ‘NIX_CONF_DIR’ environment variable is defined on
your system, and ‘guix archive’ simply honors that.

Can you confirm?

Now, we’ve honored those ‘NIX_’ variables mostly because the daemon
code, which comes from Nix, uses them, and I initially didn’t want to
diverge. Nowadays it would probably make sense to rename them.

That’s not what I see:

Toggle snippet (4 lines)
$ tar tvf guix-binary-0.9.0.x86_64-linux.tar.xz |grep /gnu/store/$
drwxrwxr-t root/root 0 1970-01-01 01:00 ./gnu/store/

Which installation method did you use?

What do you mean by “your guix symlinks”?

Thanks,

This issue is partly addressed with your patch pushed as
9dd674db017dbdc451cfd35da2dc3ce08db0726a, which renames ‘NIX_CONF_DIR’
to ‘GUIX_CONFIGURATION_DIRECTORY’.

These NIX_* variables are still in use:

NIX_AFFINITY_HACK
NIX_BIN_DIR
NIX_BUILD_CORES
NIX_HELD_LOCKS
NIX_IGNORE_SYMLINK_STORE
NIX_STORE
NIX_STORE_DIR

This is used internally:

_NIX_OPTIONS

I think those used in the build environment, NIX_STORE and
NIX_BUILD_CORES at least, are here to stay; we could provide GUIX_
aliases though they couldn’t be relied on before some time.

Not sure about the others!

Thanks,
