##Got podman issue when run podman command :
##Error: could not get runtime: kernel does not support overlay fs: overlay: the backing xfs filesystem is formatted without d_type support, which leads to incorrect behavior. Reformat the filesystem with ftype=1 to enable d_type support. Running without d_type is not supported.: driver not supported
##Reinstall podman and containers-common does not work
##Edit /etc/containers/storage.conf
vi /etc/containers/storage.conf

##Find storage.options and make sure below line is in there
[storage.options]
mount_program = "/usr/bin/fuse-overlayfs"
