Thank you for the information.  Now everything is working as you described.

See you at DebConf?

Hi,

Thanks for the report.

Indeed, this side-effect is not clearly documented and should properly
have highlighted better in the documentation.
  The reason for this is that "--onlyscripts" bypasses all the regular
detection code and assumes you have installed the init script.  Without
any -p (or similar) options, the tool will also assume to act on all
packages


What you want instead, is to use "-p<name>" in addition to
--onlyscripts, so dh_installinit only acts on the desired package.

That is, replace the above with something like:

    dh_installinit -p nginx -r --no-start --onlyscripts


On a slightly related note, in a (hopefully) not so distant future, I am
hoping to be able to retire these manual "-dbg" packages.  That is,
debhelper would be able to make them automatically.  In your particular
case, it would also have avoided this issue as dh_installinit would
ignore the automatically generated "-dbg" package.

Thanks,
