I see. This encouraged me to look at
/var/lib/portage/preserved_libs_registry, whose contents is
"x11-drivers/nvidia-drivers:0": [
"x11-drivers/nvidia-drivers-334.21-r3",
"12161",
[
"/usr/lib64/libnvidia-glcore.so.334.21",
"/usr/lib64/libnvidia-tls.so.334.21",
"/usr/lib32/libnvidia-glsi.so.334.21",
"/usr/lib32/opengl/nvidia/lib/libGL.so.334.21",
"/usr/lib64/libnvidia-glsi.so.334.21",
"/usr/lib32/opengl/nvidia/lib/libEGL.so.334.21",
"/usr/lib64/opengl/nvidia/lib/libGL.so.334.21",
"/usr/lib32/libnvidia-tls.so.334.21",
"/usr/lib64/opengl/nvidia/lib/libEGL.so.334.21",
"/usr/lib32/libnvidia-glcore.so.334.21",
"/usr/lib64/opengl/nvidia/lib/libGL.so.1",
"/usr/lib64/opengl/nvidia/lib/libEGL.so.1",
"/usr/lib32/opengl/nvidia/lib/libGL.so.1",
"/usr/lib32/opengl/nvidia/lib/libEGL.so.1"
]
]
}
So I guess this means that all the orphans come from nvidia-drivers.
So I am initially not unmerging/remerging emul-linux-x86.
That is my plan will be
move orphaned files listed above to a holding area
let revdep-rebuild do its thing
wait 30 days
delete the holding bin
Thanks for explaining.
