This looks like it broke due to breaking changes between Juju 2.9 -> 3.1:

Model       Cloud/Region         Type  Status     Machines  Units  Access  Last connection
controller  localhost/localhost  lxd   available         1      1  admin   just now
++ juju models --format yaml
++ grep '^- name:.*zaza'
++ cut -f2 -d/
+ model=
+ juju status -m
+ tee logs/juju-status.txt
ERROR option needs an argument: -m
+ juju crashdump -m -o logs/
ERROR juju: "crashdump" is not a juju command. See "juju --help".

Is it important for this branch to fix it, or would you just like it merged for convenience?

@ajkavanagh I really need to unblock our charm testing gate - I'm running this cherry-pick through with https://review.opendev.org/c/openstack/sunbeam-charms/+/903563 to check it works OK

Right, that seems reasonable. Once that passes, we can merge.

@ajkavanagh review passed testing 👍

Oh yes! It all runs upstream; I was mistakenly looking for zOSCI. Merging now.
