# openSUSE locale stage.
#
# openSUSE has NO /etc/locale.gen and NO locale-gen — that is an Arch/Debian mechanism. Locales come
# from the glibc-locale RPM (glibc-locale-base in the image only carries C.utf8 + en_US.utf8), and
# this container rootfs has no /usr/share/i18n at all, so `localedef` has nothing to compile from:
# the package really is the only way to get another locale. LANG itself lives in /etc/locale.conf,
# which we write directly — `localectl set-locale` needs a running systemd + dbus a chroot has not.
