This is a technically a bug, but it's in upstream and has no effect in
practise, so I'll close this bug report. Details below.

As of Pelican 4.7.0 which I've just submitted an update patch for,
develop_server.sh is no longer created:

$ egrep -nr "store"
pelicanconf.py:1:#!/gnu/store/nckjv3ccwdi6096j478gvns43ssbls2p-python-wrapper-3.8.2/bin/python
publishconf.py:1:#!/gnu/store/nckjv3ccwdi6096j478gvns43ssbls2p-python-wrapper-3.8.2/bin/python

This is *technically* a bug because these configuration files are
created once when the user is setting up their blog and will be used
forever after. In practise though, there's no issue since these files
are not executable - they are configuration only.

This also isn't a packaging bug in Guix, it's upstream as zimoun
suggests. Here's the first line of those files as generated by upstream
pelican-quickstart:

$ head -n1 pelicanconf.py publishconf.py 
==> pelicanconf.py <==
#!/usr/bin/env python

==> publishconf.py <==
#!/usr/bin/env python

These upstream files should not contain shebangs since they are not
executable or ever intended to be executed directly - they're config
only and have no functionality.

Ben
