+run previously-installed programs linked against glibc 2.28, you need to
+install locale data for version 2.28 in addition to locale data for 2.29:
+
+@example
+guix install glibc-locales glibc-locales-2.28
+@end example
+
+On Guix System, you can adjust the @code{locale-libcs} field of your
+@code{operating-system} form.  Run @code{info \"(guix) Locales\"}, for more
