Oh, this is due to hard links: nars don=E2=80=99t support hard links, so the
same thing is repeated several times.

--8<---------------cut here---------------start------------->8---
$ guix archive --export glibc-locales |wc -c
961328272
$ du -hsl $(guix build glibc-locales)
939M    /gnu/store/03nvilh2x4z07dxv7h13gh986vvgpnsf-glibc-locales-2.29
$ du -hs $(guix build glibc-locales)
220M    /gnu/store/03nvilh2x4z07dxv7h13gh986vvgpnsf-glibc-locales-2.29
--8<---------------cut here---------------end--------------->8---

(It does mean that we should replace hard links with symlinks, like we
do for =E2=80=98git=E2=80=99.)

Doing that with the full set of UTF-8 locales I mentioned in my previous
message, I see:

--8<---------------cut here---------------start------------->8---
$ du -hsl /gnu/store/p0knl9ggxk91x87ww702g2x78jxy1vgf-glibc-utf8-locales-2.=

--8<---------------cut here---------------end--------------->8---

To compare to:

--8<---------------cut here---------------start------------->8---
$ du -hs $(guix build glibc-utf8-locales)
6.1M	/gnu/store/n79cf8bvy3k96gjk1rf18d36w40lkwlr-glibc-utf8-locales-2.29

Thanks,
