Subject: bug#39051: nginx caching headers are broken due to epoch store timestamps
Date: Thu, 9 Jan 2020 11:52:47 +0100

I’ve been having hard-to-debug caching issues serving up static files
with nginx. It turns out this is due to nginx computing e-tag headers
from file timestamps, which are all epoch in the guix store.

I’ve fixed this on my server by applying a patch from Nix:
