# Debian locale stage. Debian generates no locales at all out of the box and the generator ships in
# the `locales` package, so: make sure locale-gen exists, list the wanted locale in /etc/locale.gen,
# generate it, and record it in /etc/default/locale — Debian's system-wide locale file, read by PAM
# on every login. /etc/locale.conf (the Arch file) is NOT it; the container image even ships
# /etc/default/locale as a symlink *to* /etc/locale.conf, so replace the link with a real file and
# keep locale.conf in step for systemd/localectl.
