Dear Maintainer,
With python-pex, an extra dependency is required on Ubuntu that isn't
required on Debian. Originally I was keeping an Ubuntu delta that
only differed by including the extra dependency in d/tests/control.
After some discussion on IRC, it was suggested that the test could do
this instead:
dpkg-vendor --is ubuntu && apt-get install -y ubuntu-drivers-common || true
That worked, but has the disadvantage that the test has to also add
the allow-root restriction. I'm wondering if there isn't a way do add
a syntax for conditional additional dependencies.
We talked about a couple of options on IRC. My thinking now is that
perhaps something like
Depends-<vendor>: foo
e.g.
Depends-Ubuntu: foo
could work. Maybe you want to generalize that into any conditional,
so for example:
Depends: @, (dpkg-vendor --is ubuntu) foo, blah
