After having installed the logstash-5.4.0.rpm on a CentOS 7 machine, the permissions under /usr/share/logstash are incorrect.
"rpm -V logstash" reports many warnings like:
.....UG.. /usr/share/logstash
This comes from the following post-install snippet:
chown -R logstash:logstash /usr/share/logstash
Is there any reason why the Logstash software is not owned by root:root like all the other pieces of software on CentOS?
