# Fedora has NO /etc/locale.gen and NO locale-gen — that is an Arch/Debian mechanism. Fedora ships
# compiled locales as glibc-langpack-<lang> RPMs, and this container image carries only C.utf8 plus
# an EMPTY /usr/share/i18n/locales, so `localedef` has no source data to fall back on either: the
# langpack really is the only way to get the locale. LANG itself lives in /etc/locale.conf, which we
# write directly — `localectl set-locale` needs a running systemd + dbus that a chroot has not.
