Hi I was experimenting in converting an lxc container to lxd. I was progressing. Then I make mistake while modifying the config file. I deleted the
Now the container does not start, even after reversing the statement.
When I start the container I get the following error:

I do not mind dumping this container. I would like to access its rootfs directory so that I can copy the changes that I made.
Any Ideas how to do it. (No I did not make a snapshot of it)
I am on ubuntu 20.04
does zsys make snapshots for lxd?
I found a bunch of snapshots like:
rpool/ROOT/ubuntu_mj0kfs/var/snap_autozsys_yjgrj5@autozsys_vwn76h Tue Apr 28 6:26 2020 0B
rpool/ROOT/ubuntu_mj0kfs/var/snap_autozsys_yjgrj5@autozsys_n5ndol Wed Apr 29 6:20 2020 0B
rpool/ROOT/ubuntu_mj0kfs/var/snap_autozsys_yjgrj5@autozsys_5fb9xg Wed Apr 29 14:39 2020 0B
Can I use those to restore the container.
