This change doesn’t hurt but it’s apparently unnecessary.

However this one is incorrect is it would lead (ice-9 string-fun) from
the host Guile to be imported into the build environment, thereby making
the result dependent on the version of Guile that is used “outside” (you
may have seen a warning like “importing (ice-9 string-fun) from the
host”.)

I tweaked that accordingly (patch attached), but that leads to a test

failure in ‘tests/guix-home.sh’ because there’s a warning about

XDG_RUNTIME_DIR not existing that goes to standard output of ‘guix home

container’:

Toggle snippet (17 lines)

+ guix home container home.scm -- false

won't execute anything. You can check if xdg runtime directory exists,

XDG_RUNTIME_DIR variable is set to appropriate value and manually execute the

script by running '$HOME/.guix-home/on-first-login'++ guix home container home.scm -- echo '$HOME'

guix home: warning: only 4.1 GiB of free space available on /gnu/store

these lines:

XDG_RUNTIME_DIR variable is set to appropriate value and manually execute the

Thoughts?

Why so? I expected modules closure to be compiled on build side and

provided to activation script via preset load-path.

BTW, I don't see this warning.

Hm, I tried with both your and my patches, but I don't get a test fail.

Ok, I found the problem. guix container uses hosts $SHELL variable,

which in my case is zsh and this makes the shell inside container not to

source ~/.profile, so on-first-login isn't executed.

I was able to reproduce test fail and message inside container.

My thoughts:

1. home container in tests must always use bash.

2. Error message should be printed to stderr.

3. Right now I experiment with elogind-less system, trying out seatd and

greetd, and try to figure out when and how process (especially shepherd)

should be started and killed. I'll share my findings on this later, but

it's very likely that we will get rid of on-first-login at all (or at

least won't source it automatically by login shell in all or some the

cases).

Do you want me to prepare patch for #2?

Best regards,

Andrew Tropin

This is true, and this causes the problem that Ludo' describes:

Two problems:

* (ice-9 string-fun) is part of Guile, so compiling it again is 
pointless (and potentially harmful, if ice-9/string-fun.scm contains a 
reference /gnu/store/.../some-target-specific-library.so)

* a form of non-determinism and non-reproducibility -- you are copying 
the modules from the Guile that 'guix' is run with, instead of always 
using the modules from the Guile that is defined inside Guix.

* additionally, maybe the inside-Guix and what-Guix-is-compiled-with 
Guile expect different behaviour of (ice-9 string-fun), causing bugs

Greetings,
Maxime.

Recipients:(name . Ludovic Courtès)(address . ludo@gnu.org)(address . 56758@debbugs.gnu.org)

Message-ID:875yjbi3ji.fsf@trop.in

Changes since v1:
- Don't use modules closure.
- Use string-append instead of format.
- Use warning instead of display.
- Hardcode SHELL=bash for home tests inside container.

Andrew Tropin (4):
  home: xdg: Use single @ intsead of @@.
  home: xdg: Skip mkdir XDG_RUNTIME_DIR in activation script.
  home: Use warning instead of display.
  tests: Make tests inside container reproducible.
