build-container-installer/Makefile

Lines 165 to 166 in df936e3

	mv /etc/rpm/macros.image-language-conf /etc/rpm/macros.image-language-conf.orig || true
	cp /etc/os-release /etc/os-release.orig || true

build-container-installer/Makefile

Lines 187 to 188 in df936e3

	mv -f /etc/rpm/macros.image-language-conf.orig /etc/rpm/macros.image-language-conf || true
	mv -f /etc/os-release.orig /etc/os-release || true

I believe when this was originally working properly, we just straight up removed the language macros file and did not move it and restore it.
