Please note:
The "rabbitmqctl" command must be run as the %%RABBITMQ_USER%% user,
with a real shell, and with the ${HOME} environment variable set to that
user's real home directory.

su users can do something like this:
 # env HOME=/home/%%RABBITMQ_USER%% su -m %%RABBITMQ_USER%% -c 'rabbitmqctl ...'

sudo users can do something like this:
 # sudo -H -u %%RABBITMQ_USER%% rabbitmqctl ...
