I am trying to reproduce this: Is it possible to mount nested ZFS datasets from within a container? - #4 by stgraber
My host is Apline Linux 3.20 with the 6.6.57-0-lts Kernel and ZFS zfs-2.2.5-1.
Edit: Incus 6.0.2
I get at the end in the container running zfs list:
Permission denied the ZFS utilities must be run as root.
Is this because Alpine’s ZFS is further ahead and Ubuntu’s 2.2.2 is not compatible?
cs0001:~# incus launch images:ubuntu/24.04 u1
Launching u1
cs0001:~# incus config device add u1 extra disk pool=base-pool source=u1-extra path=/mnt
Device extra added to u1
cs0001:~# incus exec u1 bash
root@u1:~# apt install zfsutils-linux
