Libvirt (LGPLv2+) has to make decisions based on what file system is hosting a guest image (guest migration behaves differently depending on whether the guest disk image resides on a local or a shared file system). Licensing may be a sticking point - coreutils' list is currently GPLv3+, but is derived from the kernel (GPLv2), and libvirt cannot reuse it unless it is further relaxed to LGPLv2+.
