-install zfs-utils and disable zpool auto-scrub,
+install linuxXY-zfs(for latest installed kernel),
 change timezone to Prague,
 crypt swap partition with ecryptfs-utils,
-crypt some partition with dmcrypt to use with /var/lib/lxd and LXD ZFS storage,
+crypt some partition with dmcrypt to use with /var/snap/lxd/common/lxd/* and LXD ZFS storage,
 add some config to sysctl.conf,
-disable lxd service,
-delete everything in /var/lib/lxd/*,
-delete netplan, install ifupdown,
-configure bridged networking (you can put LXD container to your network simple by add br0 to container),
