Would you accept patches for this?
I have noticed this as well e.g. whenever Debian ships a new openssh-server package, I've had to manually run the command shown on the hardening guide to remove modulus below 3272-bit all over again. For what it's worth, I fully agree with Colin that some of Joe Testa's recommended hardening measures lack proper justification. Damien Miller noticed the same thing, when I recently asked him to comment on the recommendations. I however think that Daniel's proposal for a patch that better takes into consideration possible local deviations from Debian defaults might be a good compromise between adopting 'ssh-audit' paranoia for the Debian package and letting administrators adopt them if they wish.
