# According to
# https://www.suse.com/documentation/sles-12/book_sle_admin/data/sec_suse_l10n.html,
# variables in /etc/sysconfig/language are supposed to be passed to
# the users' shell *only*. However it seems that there has been some
# confusion and they ended up configuring the system-wide locale as
# well.  The logic followed by systemd was implemented in commit
# 01c4b6f4f0d951d17f6873f68156ecd7763429c6, which was reverted. The
# code below follows the same logic to migrate content of
# /etc/sysconfig/language into locale.conf.
