Yet another service up seems undesirable indeed.  Is it really needed?
This existing query reveals the problem:

https://packages.debian.org/search?lang=en&suite=sid&arch=any&mode=path&searchon=contents&keywords=%2Fusr%2Finclude%2Fref_array.h

Iterating that online query over all filenames in a newly built package
from a Salsa job seems excessive though.

A smaller tool that merely downloads Contents-* files doesn't seem
entirely unreasonable?  The Contents* files are <<100MB each, which
isn't a lot compared to all the rest of network noise during a Salsa
build pipeline.

Is there a tool that finds file conflicts like this already?  This is a
fairly simple and basic query.  Doesn't 'apt' have something already?

jas@frallan:~$ rm Contents-amd64*
