bug#50945: Guix home: No such file or directory: "/run/user/1003/on-first-login-executed"

[Jan Nieuwenhuizen]

Hi,

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

--8<---------------cut here---------------start------------->8---
Backtrace:
           2 (primitive-load "/home/guix/.guix-home/on-first-login")
In ice-9/ports.scm:
   461:11  1 (call-with-output-file "/run/user/1003/on-first-login-…" …)
In unknown file:
           0 (open-file "/run/user/1003/on-first-login-executed" "w" …)

ERROR: In procedure open-file:
In procedure open-file: No such file or directory: 
"/run/user/1003/on-first-login-executed"
--8<---------------cut here---------------end--------------->8---

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.

Greetings,
Janneke
