Gen2 container update - Githubissues

=> x86_64 arch is not there in the lxc container list, instead we have to create amd64. (Can list all the available arch by "sudo lxc-create -t download -n <name>)
=> Container will be created at "/mnt/store0/lxc/lib/lxc/", config and rootfs both.
=> Required binaries/scripts for creating container I kept at "/mnt/store0/ROOT" (debootstrap, wget https support (compiled busybox and created softlink), gpgv, container_mngr_lxc.sh, sha256sum, rsync trick to ignore ACL support request command "-A")
=> Exported PATH from /mnt/store0/etc/fmadio.rc
export PATH=/mnt/store0/ROOT/usr/bin:/mnt/store0/ROOT/usr/sbin:$PATH

=> Here is the script I wrote to manage the containers:

fmadio@fmadio20-162:~$ sudo /mnt/store0/ROOT/usr/sbin/container_mngr_lxc.sh
Usage: sudo /mnt/store0/ROOT/usr/sbin/container_mngr_lxc.sh <list | create | destroy | init | stopall | stop>
        list           To list the containers
        init           To initialize / start all containers
        stopall        To stop all the containers
        create <name>  To create new container based on ubuntu/bionic/amd64 with named specified
        stop <name>    To stop the specific container
        destroy <name> To destroy the specific container
