Comment 1 for bug 2063037

Additionally:

The value of LANGUAGE is restored to the correct value after one reboot, i.e. the wrong value appears only on the first boot after installation.

and the outputs of locale after reboot again:
```
LANG=zh_CN.UTF-8
LANGUAGE=zh_CN
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY="zh_CN.UTF-8"
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER="zh_CN.UTF-8"
