bug#26752: Ansible & others' problems with wrapped '.ansible-real' scripts

[Jelle Licht]

Hi,

I had some problems getting current ansible package to work. It seems that the bin/ansible script which is created as part of the python-build-system via a call to `wrap-program' interferes with certain expectations ansible has regarding how it and its subcommands are called.

This mechanism does not work well with our generated created .ansible-real. See [1] for a similar issue that has since been worked around in the newest version of ansible.

For now, I have a similar workaround that add some guix-specific checks to ansible looking for being called as .ansible-real, though I do consider this a hack. This problem is indicative of a bigger issue: the fact that wrap-program currently leads to subtle bugs for lots of scripts. There has been some noise on #guix about solving this problem in general.

Thanks,

Jelle
