Throughout the installation guide for the broker commands are prefixed with sudo. Doing this creates the broker as root which then requires the broker to run as root and several of the broker commands to then be run as root; for example:

/var/lib/amq7/mybroker/bin/artemis run
/var/lib/amq7/mybroker/bin/artemis producer
/var/lib/amq7/mybroker/bin/artemis consumer

must all be run as root privileges.

The ports being used by Artemis are all well above the Privileged port range, is there a reason why Artemis must run as root?
