Bug Description
Hi,
Not sure where to post/look for help with this. I've had a bit of a look and I'm unable to find something similar, so would appreciate some help.
Looks like this might be due to changed in block_meta.py in curtin.
I have a script that generates a custom ISO with ZFS root based on the live server ISO install:
https:/
It adds the ZFS packages to the installer and installs them at install time allowing for a ZFS root install to be done. This had been working for all releases from 20.04 and later, but recent changes to the installer have broken it. It still works fine with the LTS releases, but the daily builds and 23.10/24.04 betas are now failing.
It looks like the issue with the updated installer and parsing of the cloud init config file. It creates the ZFS pool and filesystem and mounts it, and then fails when it hands over to phase where it copies the base image to filesystem. It looks like is not returning the correct volume ID for the installer when I debug the crash logs from the installer.
This is the failure point on noble/24.04:

Some additional information:
This config works for 20.04, 22.04, and 23.04, and fails on daily builds of 22.04 and later.
block_meta.py appears to have changed a bit since last year.
