[Message part 1 (text/plain, inline)]
Some of the build nodes behind the Berlin build farm have a childhurd
which can build packages. Unfortunately, the symlink from
/etc/guix/machines.scm to the generated file in the store to setup
offloading has been garbage collected on several of the machines.

Indeed. Here’s an example:
--8<---------------cut here---------------start------------->8---
root <at> hydra-guix-108 ~# guix gc -R $(readlink -f /run/current-system) |grep machines.scm
/gnu/store/xg26iis3ydik6zxqk24cyk7h9zli1d25-machines.scm
root <at> hydra-guix-108 ~# ls -l /etc/guix/machines.scm
lrwxrwxrwx 1 root root 56 Mar 7 11:53 /etc/guix/machines.scm -> /gnu/store/1171q4xhph07ll3mlzlg7igcwg3c98i1-machines.scm
root <at> hydra-guix-108 ~# stat -L /etc/guix/machines.scm
stat: cannot statx '/etc/guix/machines.scm': No such file or directory
--8<---------------cut here---------------end--------------->8---
Here /etc/guix/machines.scm points to a different ‘machines.scm’ than
the one that is current. The old one was removed last week:
--8<---------------cut here---------------start------------->8---
root <at> hydra-guix-108 ~# zgrep 1171q4xhph07ll3mlzlg7igcwg3c98i1 /var/log/mcron.log.1.gz
2024-03-27 03:00:05 23100 guix gc -F 150G: [46%] deleting '/gnu/store/1171q4xhph07ll3mlzlg7igcwg3c98i1-machines.scm'
--8<---------------cut here---------------end--------------->8---
The /etc/guix/machines.scm link was created on the last deployment
though:
--8<---------------cut here---------------start------------->8---
root <at> hydra-guix-108 ~# ls -l /etc/guix/machines.scm
lrwxrwxrwx 1 root root 56 Mar 7 11:53 /etc/guix/machines.scm -> /gnu/store/1171q4xhph07ll3mlzlg7igcwg3c98i1-machines.scm

Could it be that the “wrong” activation snippet was run by ‘guix
deploy’? Here we see the right one:
--8<---------------cut here---------------start------------->8---
root <at> hydra-guix-108 ~# grep machines.scm $(guix gc -R $(readlink -f /run/current-system) |grep activate-service)

Turns out that both files are identical, but:
• /gnu/store/1171q4xhph07ll3mlzlg7igcwg3c98i1-machines.scm is built
with
/gnu/store/g8p09w6r78hhkl2rv1747pcp9zbk6fxv-guile-3.0.9/bin/guile
(‘guile-final’ ungrafted);
• /gnu/store/xg26iis3ydik6zxqk24cyk7h9zli1d25-machines.scm is built
with
/gnu/store/g49b4v7dff8xwfi7wpi8pps1ixhld3n7-guile-3.0.9/bin/guile
(‘guile-final’ grafted).
As it turns out, <scheme-file> (used for “machines.scm”) uses
‘gexp->file’, which, unlike ‘gexp->script’, does not default to
(default-guile). That probably explains the difference.

I believe this is fixed by b30b838d5055e36be19d030db28838fec4474d98.
