   2 # Since SIGUSR2 upgrades do not work under systemd, this service file
   3 # allows starting two simultaneous services during upgrade time
   4 # (e.g. public-inbox-httpd@1 public-inbox-httpd@2) with the intention
   5 # that they take turns running in-between upgrades.  This should
   6 # allow upgrading without downtime.
   7 # For servers expecting visitors from multiple timezones, TZ=UTC
   8 # is needed to ensure a consistent approxidate experience with search.
