Fixed by simply letting it through:

  https://git.savannah.gnu.org/cgit/guix/maintenance.git/commit/?id=3D8859a=
f255f4041f90f630094c6ec81227b554904

However note that it=E2=80=99s a 2.2=C2=A0GiB file.  I think it=E2=80=99s O=
K for hydra to
serve it, in particular because =E2=80=98guix publish=E2=80=99 does almost =
no processing
on that file since it=E2=80=99s already compressed.  So the only cost is
bandwidth.

(The =E2=80=98texlive-texmf=E2=80=99 binary remains unavailable on hydra be=
cause it=E2=80=99s
marked as non-substitutable.)

Other options that came to mind were:

  1. Mark the texlive-texmf source derivation as non-substitutable,
     which would have required fiddling with =E2=80=98url-fetch=E2=80=99 to=
 pass
     #:substitutable? #f to =E2=80=98raw-derivation=E2=80=99.  Everyone wou=
ld have
     downloaded from the upstream FTP site.

  2. Add a =E2=80=98--hide=3D.*texlive-texmf*=E2=80=99 option to =E2=80=98g=
uix publish=E2=80=99, which
     would prevent it from publishing narinfos for store items that
     match the regexp.
