I have multiple broken generation. On one that now for a third time
(on old generations without Ludo’s patches) led to a locked
/etc/shadow after booting I changed the line
(let ((pid (fork+exec-command (list udevd))))
in gnu/services/base.scm to, I believe, this:
(let ((pid (fork+exec-command (list udevd "--debug-trace"))))
(I am unsure if this is the same broken generation as on my first
report of the issue. I may have gotten confused.)
This is unbootable, correct would have been --debug and not
--debug-trace.
I may also have changed my syslog configuration to the incorrect
(modify-services %desktop-services
(syslog-service-type config =>
(syslog-configuration
(inherit config)
(config-file
(plain-file "my-syslog.conf" "
# Log all error messages, authentication messages of
# level notice or higher and anything of level err or
# higher to the console.
# Don't log private authentication messages!
* /var/log/full
[…]")))))))
Correct would have been *.* instead of * This latter error is
without relevant effect I believe.
I will try to find the /gnu/store files for this generation.
Danny’s suggestion to `chattr +i /etc/shadow` leads to an error with
rename-file trying to rename an empty /etc/shadow.Gi… temporary file
on both this old broken and on healthy generations.

If I cannot find a more deterministic way, I will try making (guix
build accounts) print the content of shadow.
