I’d like to be able to rehearse zfs operations safely within an lxc container. I would be using file-based zpools within the container’s file-system. I don’t want to mount external pools/datasets.
I’m having some serious failures with apt install zfsutils-linux see Bug #1982994 “zfsutils-linux fails to install in lxc ubuntu 20.0...” : Bugs : zfs-linux package : Ubuntu
installing on 22.04 guest has different failures.
I have lxc 5.4 on an Ubuntu 20.04 host.
Can this be achieved simply?
Cheers…

Hi,
You can try with the vm, because of kernel restrictions.
lxc launch images:ubuntu/22.04/cloud --vm
