I agree with Barry that fixing it in the helpers would be the right way
to go.
Alas, I don't have the time to work on the helpers either, but as a
proof that it works and no disaster is immediately apparent, i've gone
ahead and fixed up getmail (which is python2-only) to use the python2
shebang line, and has an explicit dependency on python2.7 instead of
python.
Please take a look at getmail 5.5-3 if you're interested in what the
package looks like.
If dh_python2 got updated to:
A) force the python2 shebang line for any scripts installed in bin or
sbin, and
B) to evaluate the ${python:Depends} substvar to python2.7 instead of
the current python:any (<< 2.8), python:any (>= 2.7.5-5~)
Then i'd be happy to revert the packaging changes to getmail and fall
back to the dh defaults :)
I'm not immersed enough in dh-python to know how to make those changes
myself right now, though.
