Hi,

When using su or sudo to enter an account managed by guix home, I get

this error

Toggle snippet (11 lines)

Backtrace:

In ice-9/ports.scm:

Upon a console login or ssh login, /var/run/1003 is created and all is fine.

See below for the scenario, home-minimal.scm is attached.

[ Cc Andrew who did most of the work on Guix Home ]

I think this is because Guix Home relies on $XDG_RUNTIME_DIR to be
defined, otherwise it falls-back to /run/user/UID.  But it looks like
/run/user/UID isn’t created when using ‘su’ to login.  I don’t really
know how these things work under the hood; maybe using $XDG_RUNTIME_DIR
isn’t best idea.

Thank you for a very detailed report.

pam_elogind doesn't create a session, when the login shell spawned by

sudo or su => XDG_RUNTIME_DIR not get created => this message appears.

I think we can omit execution of any processes by on-first-login script

in case session wasn't created. Added the check:

Use (unless …) instead of (when (not …)…).

It would be good to tell the user how they could manually run the

script, that way they could manually set/create $XDG_RUNTIME_DIR and run

the script.

"XDG_RUNTIME_DIR doesn't exist; the 'on-first-login' script won't

execute anything. You can manually execute the script by running

'$HOME/.guix-home/on-first-login'

WDYT?

Applied, with a “Fixes” line in the commit log. However…

This pattern is problematic because this text is not internationalized

(not subject to translation). Part of caring about users in Guix

implies ensuring that all messages are internationalized.

The fact that the text is embedded in a generated script makes it a

little trickier. In the installer, we address that by using the message

catalog of the ‘guix’ package like so:

#~(begin

(bindtextdomain "guix" (string-append #$guix "/share/locale"))

(textdomain "guix")

(setlocale LC_ALL ""))

The downside is that the script ends up depending on the ‘guix’ package;

we could optimize that later on.

At any rate, for these cases where you cannot avoid having messages

printed by generated scripts such as this one, the solution would be to:

1. Add calls to ‘bindtextdomain’ and ‘textdomain’ as above

(‘setlocale’ no longer needs to be called explicitly).

2. Import (guix i18n) and wrap messages in ‘G_’ (or ‘N_’) calls.

3. Ensure that each file that uses ‘G_’ or ‘N_’ is listed in

po/guix/POTFILES.in.

Could one of you take a look? :-)

I tweaked the wording and applied. Thank you!
