Using system java: /usr/sbin/java
Usage: system-install [OPTIONSFILE] [STARTUPTYPE] [VERSION]
NOTE: These arguments are ordered, and co-dependent
OPTIONSFILE: Full path to a startup.options file
OPTIONSFILE is required if STARTUPTYPE is specified, but otherwise looks first
in /etc/logstash/startup.options and then
in /usr/share/logstash/config/startup.options
STARTUPTYPE: e.g. sysv, upstart, systemd, etc.
OPTIONSFILE is required to specify a STARTUPTYPE.
VERSION: The specified version of STARTUPTYPE to use. The default is usually
preferred here, so it can safely be omitted.
Both OPTIONSFILE & STARTUPTYPE are required to specify a VERSION.
