Comment 25 for bug 1419061

It's the ubuntukylin-default-settings package which modifies /etc/os-release:

 $ grep -r 'os-release' *
debian/ubuntukylin-default-settings.postrm: sed -i "/NAME/s/Ubuntu Kylin/Ubuntu/g" /etc/os-release
debian/changelog: * Be more specific in replacing Ubuntu in /etc/os-release to prevent
debian/changelog: * Use os-release instead of ubuntukylin-release
debian/ubuntukylin-default-settings.preinst: sed -i 's/\(NAME="Ubuntu\)"/\1 Kylin"/' /etc/os-release
debian/ubuntukylin-default-settings.preinst: sed -i 's/\(PRETTY_NAME="Ubuntu\) 1/\1 Kylin 1/' /etc/os-release

So that package should also contain the apport setup in comment #23.
