LXD INIT not work for now, i dont have time to fix it. So, after installation via script, you need to run lxd init manually and set up it like script.

Features:

copy_containers -> script for easy bulk container migrate via SSH between instalations of usl-mm, is also possible use it in non-interactive mode with parameters in this order: container-name, destination-host, destination-port(optional)

zfs-backup-mm-example-config -> example config for zfs-backup-mm script, that backup all running containers, except those with "testing" or "deluge "in container name.

setup-usl-mm_install_requirements -> install dialog utility

setup-usl-mm

1. Pre-reboot script -> install zfs-utils, change timezone to Prague, crypt swap partition with ecryptfs-utils, crypt some partition with dmcrypt to use with /var/snap/lxd/common/lxd/* and LXD ZFS storage, add some config to sysctl.conf, disable snapd.lxd service, delete everything in /var/snap/lxd/common/lxd/*, 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 1536MB, 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 snapd.lxd service and delete everything in /var/snap/lxd/common/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), install htop mc zfsnap smartmontools screen and pv
