We already only include .conf files in fluent.conf:
(fluentd)[fluentd@cpu-e-1041 /etc/fluentd]$ cat fluent.conf
@include input/*.conf
@include filter/*.conf
@include format/*.conf
@include output/*.conf
so this change should not cause ill effect. This works because of the
merge option in config files:
merge: merges the source directory into the target directory instead of
replacing it. Boolean, defaults to false.
