[debhelper-devel] Bug#795193: debhelper: dh_installinit --onlyscripts should generate the debhelper scripts for the first package only

[Jose M Calhariz]

Package: debhelper
Version: 9.20150628
Severity: normal

With source packages that generate <name>-dbg package for debug
symbols, they generally use dh_installinit without problems.  The
debhelper scripts are generated for the first package only.

But when is added the option "--onlyscripts" it generates debhelper
scripts for both packages.  This means that when installing <package>
and <package>-dbg, it is not possible to remove <pakage>-dbg.  The
postrm script of <package>-dbg tries to remove the init script that
belongs to <package>.

Using debhelper compatibility mode 5.

This bug was reproduced using nginx package v0.7.67.  From debian/rules:

binary-arch: install
        dh_testdir
        dh_testroot
        dh_installchangelogs CHANGES
        dh_installdocs
        dh_installinit -r --no-start --onlyscripts
        dh_installman debian/nginx.1
        dh_installlogrotate
        dh_link
        dh_strip --dbg-package=nginx-dbg
        dh_compress
        dh_fixperms
        dh_installdeb
        dh_shlibdeps
        dh_gencontrol
        dh_md5sums
        dh_builddeb


Adding the option --onlyscripts breaks the package.
