Bug#880095: /usr/bin/dh_girepository: please support Rules-Requires-Root: no

[Simon McVittie]

Package: gobject-introspection
Version: 1.54.1-1
Severity: wishlist
File: /usr/bin/dh_girepository

I tried converting src:flatpak to Rules-Requires-Root: no, which skips
use of fakeroot, instead running the entire build as the ordinary user and
telling dpkg-dev to consider all files in the tarballs inside the .deb to be
owned by root:root. However, that fails:

make[1]: Leaving directory '/<<PKGBUILDDIR>>'
   dh_strip
   dh_makeshlibs
   dh_shlibdeps
   dh_girepository
install: cannot change owner and permissions of 'debian/gir1.2-flatpak-1.0/DEBIAN': Operation not permitted
dh_girepository: install -o 0 -g 0 -d debian/gir1.2-flatpak-1.0/DEBIAN returned exit code 1
debian/rules:11: recipe for target 'binary' failed

If dh_girepository just used "install [-m MODE] -d DEST" and
"install [-m MODE] SOURCE DEST" instead of adding -o 0 -g 0, this would
probably work, because the default for install(1) is to install the files
owned by the current uid and the current primary gid.
