+Subject: templates: Filter out POSIX locale for translation
+
+The POSIX locale is default or native operating system's locale
+identical to the C locale, so no translation to human speaking languages
+are provided. For this reason we should filter out LANG=POSIX as well as
+LANG=C upon generating grub.cfg to avoid looking up for it's gettext's
+message catalogs that will consequently result in an unpleasant message:
+
+  error: file `/boot/grub/locale/POSIX.gmo' not found

+Subject: templates: Filter C.UTF-8 locale for translation
+
+In addition to C locale there is also C.UTF-8 locale now. Filter that as
+well, by using ${grub_lang}, which contains a stripped value.
+This fixes the following message and resulting boot failure:
+
+    error: file `/boot/grub/locale/C.gmo' not found.
