delete netplan, install ifupdown,
configure bridged networking (you can put LXD container to your network simple by add br0 to container),
create zpool with ashift=12,
set compression=on on crypted zpool,
configure zfs cache min 256MB max 1024MB,
do dist-upgrade,
create /root/onstart script to decrypt crypted parition with password and start lxd (you need start this script on every reboot),
reboot
2. Post-reboot script ->
for sure, stop lxd service and delete everything in /var/lib/lxd/*,
exec /root/onstart to decrypt partition and import zpool,
configure LXD to use encrypted partition as storage,
add some config to /root/.screenrc (for gnuscreen utility),
