It looks like ElasticSearch, LogStash, and Kibana RPMs put systemd files in different places. Why is that?
I did a deploy of all 3 on a fresh VM. I expected all three files to be in the same place, but ElasticSearch puts its file in /usr/lib/systemd/system/elasticsearch.service
[root@elk elasticsearch]# ls /etc/systemd/system/logstash.service
/etc/systemd/system/logstash.service
[root@elk elasticsearch]# ls /etc/systemd/system/kibana.service
/etc/systemd/system/kibana.service
[root@elk elasticsearch]# ls /etc/systemd/system/elasticsearch.service
ls: cannot access /etc/systemd/system/elasticsearch.service: No such file or directory
[root@elk elasticsearch]# ls /usr/lib/systemd/system/elasticsearch.service
/usr/lib/systemd/system/elasticsearch.service
[root@elk elasticsearch]#
