5. Make lxc image:

   lxc-create -n <image name> -t loongnixdebian --dir=/path/to/rootfssave # <--use absolute path here!

6. Clean-up lxc rootfs and more custom:

   cd /path/to/rootfssave
   
   # clean up:
   
   rm -rf ./var/cache/* ./tmp/* ./var/log/* ./var/tmp/* ./var/lib/apt/lists/*

7. Export to lxc tarball:

   cd /path/to/rootfssave
   
   tar czvf ../loongnix.tar.gz ./*
