The dracut produced initial ram filesystem offers a large variety of storage configurations, see https://github.com/dracutdevs/dracut/blob/master/dracut.cmdline.7.asc#booting-live-images. One new configuration with OverlayFS will allow the overlay to consume the whole USB flash drive file system if the USB flash drive file system is formatted with ext4 or xfs file system types. The OverlayFS configuration is less mature than the Device-mapper configuration, so experimental feedback is welcome. | The dracut produced initial ram filesystem offers a large variety of storage configurations, see https://github.com/dracutdevs/dracut/blob/master/dracut.cmdline.7.asc#booting-live-images.
