# the "conf" subdirectory. So symlink $out/conf to some directory
# outside of the Nix store where we want to keep this stateful info.
# Note that different instances of the frontend will therefore end
# up with their own copies of the PHP sources. !!! Alternatively,
# we could generate zabbix.conf.php declaratively.
