After a recent update, portage reported the following to me: !!! existing preserved libs: >>> package: net-fs/libnfs-2.0.0 * - /usr/lib64/libnfs.so.8 * - /usr/lib64/libnfs.so.8.0.0 * used by /usr/bin/qemu-img (app-emulation/qemu-2.10.1-r1) * used by /usr/bin/qemu-io (app-emulation/qemu-2.10.1-r1) * used by /usr/bin/qemu-nbd (app-emulation/qemu-2.10.1-r1) * used by /usr/bin/qemu-system-x86_64 (app-emulation/qemu-2.10.1-r1) Sure enough, net-fs/libnfs has a subslotted SLOT= value in its ebuilds but app-emulation/qemu does not use := (or :0=) on the dependency atoms. Please add.
