The following tools only apply -X in case 1. This is useful. dh_autoreconf dh_fixperms dh_installchangelogs dh_md5sums dh_prep dh_shlibdeps dh_strip dh_dwz dh_makeshlibs dh_link The following tools apply -X to both case 1 and 2, but 2 is never used in practice.I suggest dropping support for case 2. dh_clean\s.*(?:-X|--exclude)) shows 138 results. All of them excluding paths matching the default pattern, with no or unrelated command line arguments. The implementation applies -X to config file, but not to command line arguments, and no none seems to have noticed. Job already half done :-). dh_compress seems similar, though I have not checked each one of the 1536 results. Only 3 tools frequently use --exclude to refine command-line or config-file patterns. dh_install (and its old variant dh_movefiles, 1 result) dh_installdocs dh_installexamples > 2) The case you described above where people want "all the files in > foo except bar". After reading many examples, I realize how this can be convenient ("dh_installexamples -X.cvsignore"). > 1) Ignore files/paths from the config file that are conditionally > built. This is usually observed via the following pattern: > [...] In my opinion, such a construct is an abuse of -X. It is better to * remove foo from debian/pkg.install (tell the truth) * add foo to debian/not-installed (tell the truth) * use a positive selection: (each negation hinders readability) PKG_INSTALL := ifeq ... PKG_INSTALL += foo endif [...] dh_install --package=pkg $(PKG_INSTALL) dh_install --remaining-packages The difference is cosmetic for the maintainer, but not in favor of -X. > [executable config files and dh-exec] If dh-exec finds a new maintainer, it may be the best option to implement exclusions outside debhelper (#498067 has a pending patch). > If you can convince the remaining consumers of --ignore to migrate > away, then I am happy to drop the option when we release debhelper 12. This seems possible: * gutenprint: reported as #895659. * ocaml: patches #877267 as a side effect. * lintian: in t/tests/debhelper-dh-exec/ https://salsa.debian.org/lintian/lintian/commit/7ed7a25acf523d2a820785841be96a01814c5f2f If I understand well, it should be sufficient to * rename debian/debian/docs to debian/debian/mime. * replace lines 6-9 of debian/debian/rules with "override_dh_installmime:" * replace "debian/docs" with "debian/mime" at end of line 8 in the tags file. As the author of the commit, you should be able to answer :-)
