I'm working with Ubuntu 20.40, where I'm creating an ISO with the user-data/meta-data on the image, then booting a VMware VM off it. I watch the output, it seems to create the logical volumes and mount points; it installs software, the user I configured, updates etc., but every time I end up with a filesystem I didn't ask for. I've put this through YAML validators, validated it with cloud-init, compared it to other configs and I cannot figure out what the problem is.
I stripped it all down to just the basics and it still does the same thing. Here's the user-data (sanitized):

- {path: /var/log/audit, device: format-5, type: mount, id: mount-5}
When I'm done and I reboot the VM, the filesystem looks like this. There is plenty of disk space (250GB) and 10GB of RAM. Resources aren't the issue. The cloud-init logs don't say anything obvious to me (there's a lot in there):

I can't see what's going wrong here.
Thanks!
