That showed nothing obvious to me; the log it spits out is about 3MB
(~320k compressed with zstd) I could attach if it is useful...
I did notice SHELL=/bin/bash, and tried an experiment:
$ SHELL=/gnu/store/87kif0bpf0anwbsaw0jvg8fyciw4sz67-bash-5.0.16/bin/bash guix
shell --check -D guix
guix shell: checking the environment variables visible from shell
'/gnu/store/87kif0bpf0anwbsaw0jvg8fyciw4sz67-bash-5.0.16/bin/bash'...
guix shell: All is good! The shell gets correct environment variables.
So, somehow the value of SHELL and/or the user's default shell is
triggering the issue?
