Hello,

=E2=80=98render-narinfo/cached=E2=80=99 in =E2=80=98guix publish=E2=80=99 u=
ses =E2=80=98hash-part->path=E2=80=99 to go
from /xyz.narinfo to, say, /gnu/store/xyz-guile-2.2.4.

The problem is that =E2=80=98hash-part->path=E2=80=99 is an RPC that works =
only if xyz
corresponds to a live item; in other cases, it returns the empty
string.  Consequently, if /gnu/store/xyz-guile-2.2.4 has been GC=E2=80=99d,
=E2=80=98guix publish=E2=80=99 returns 404 for /xyz.narinfo, even if it act=
ually has the
narinfo somewhere in cache.

This defeats the intended behavior of =E2=80=98--cache=E2=80=99 and =E2=80=
=98--ttl=E2=80=99.

Ludo=E2=80=99.
