Hello,

Paul <paul@denknerd.org> reported on IRC that his guix behaved strangely. Upon
investigation we found that the following happens (on a Guix system), when logged
in as regular user (not root):

$ readlink ~/.config/guix/current
/var/guix/profiles/per-user/dannym/current-guix
$ sudo -E guix pull
$ readlink ~/.config/guix/current
/var/guix/profiles/per-user/root/current-guix

You can also rm -f ~/.config/guix/current after that and do everything above
again and it will happen again. It even happens when guix pull has nothing to
do.

That doesn't seem right. We should at least try to prevent this from happening,
or warn or something.

The guix package manager that did that is:

ISTM it looks like a bug that should be fixed[1], urgently, not just warned about :)
[1] eliminated from the possibility of happening :)

I find it peculiar that root (sudo -i) looks like it's using swedish locale
("aktuell" is swedish for "current") with the rest of the output identical.
(Hm, maybe that's also Norwegian ;-)

If describe is describing two things that are identical end values of
readlink -f thing{1..2}, I think it would be helpful to show the thing{1..2}
profile links it's using.

BTW, what would sudo guix describe without the -E (preserving user environment) have produced?

What is expected to happen in this case? Why would one want to use an
unprivileged environment with privileges to do `guix pull`, which is a
per-user operation?

Paul did not know that it is a per-user operation.

I did almost exactly the same thing when I was a new guix user.
That's pretty much what one is used to from Debian etc.

I don't really know whether it should do anything useful, but the current
situation is seriously weird.

I see. Coming from Debian, I also had trouble learning the differences
between various options of sudo, and also the differences between login
shells, interactive shells, etc. They don't matter on Debian, but they
do matter for Guix.

Considering how often people stumble on this, I've been wondering if
Guix should handle privilege escalation internally, rather than asking
users to learn these arcane details of Unix.

Systemd does that. For example, given an operation that requires
privileges, if I attempt to run it without privileges, it will use
polkit (I think) to escalate safely. It's optional and not all distros
enable it by default. It looks like this:

------
$ systemctl restart guix-daemon
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to restart 'guix-daemon.service'.
Authenticating as: leo,,, (leo)

That's some weird guix pull state.

The culprit, I think, is this:

(define (ensure-default-profile)
(ensure-profile-directory)

;; In 0.15.0+ we'd create ~/.config/guix/current-[0-9]*-link symlinks. Move
;; them to %PROFILE-DIRECTORY.

;; XXX: Ubuntu's 'sudo' preserves $HOME by default, and thus the second

(unless (or (getenv "SUDO_USER")
(string=? %profile-directory
(dirname
(canonicalize-profile %user-profile-directory))))
(migrate-generations %user-profile-directory %profile-directory))

where

%profile-directory = "/var/guix/profiles/per-user/dannym"
%user-profile-directory = "/home/dannym/.config/guix/current" (which is a
symlink to /var/guix/profiles/per-user/root/current-guix)

Ohh, yeah, sudo without "-E" works fine (sudo guix pull, too).
