>> Hello Guix,
>>
>> This patch fixes some uses of relocatable git (e.g.  octopus merge). 
>> Previously, guix pack would wrap all files in "bin", "sbin", and "libexec",
>> even non-executable files.  This would cause issues for git when its shell
>> scripts in libexec would try to source other shell files that had been
>> wrapped and were no longer a valid shell file.
>
> Good catch!
>
>> I feel like a test should be added to tests/guix-pack-relocatable.sh, but
>> I'm not sure how to do that while keeping the test lightweight.  Suggestions
>> welcome.

> Not sure how to do that.  Since ‘guix pack’ accepts manifests, you could
> have a manifest containing a ‘computed-file’ with a file that shouldn’t
> be wrapped, and then you could ensure that’s indeed the case.  Or you
> could try with ‘git-minimal’ or some other package that exhibits the
> problem?
