# 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.
