When set, runqemu appends '-dbg' to the IMAGE_LINK_NAME used to locate the rootfs tarball for NFS extraction, allowing use of the debug rootfs variant. QB_FSINFO: additional filesystem metadata, as a space-separated list of "fstype:flag" entries, e.g., "wic:no-kernel-in-fs tar:rootfs-dbg" Supported flags include "wic:no-kernel-in-fs" or "wic:kernel-in-fs" to select whether a WIC image contains the kernel in the filesystem, and "tar:rootfs-dbg" to tell runqemu to use the debug rootfs image.
