First you need to teach the Live Image Environment how to speak ZFS
Code:
sudo su -
apt install -y zfsutils-linux
Then find out what ZFS pools can be imported
Code:
zpool export -a
zpool import
Doing that command will list all pools that are not already imported. Lets say the pool you wanted to use was MyPool. Then to import it
Code:
zpool import -f -N -R /mnt MyPool
Repeat that for any other pools that you want to mount...
Then list the dataset structure
Let's say your recognise the base dataset structure as something like
Code:
zfs list
MyPool/DATA/ubuntu_2404
Then you would do
Code:
zfs mount MyPool/DATA/ubuntu_2404
zfs mount -a
You should now be able to access any files within that pool's filesystem, under the /mnt folder.
Note that those instructions are just to access the files, not to repiar an OS within that, which would then take chrooting into that filesystem.
