@jameinel Great investigation! Thanks for looking into this. Very interesting that it boils down to the start time of the binary and in that case all of the Juju tools. It is just juju-log that my charms called more than anything else ( that’s what happens when you set -x in a bash script and log the output 
).
At least that seems like a rather simple and not majorly architectural change to Juju if we had to split it out to a separate command.
