DEVPTS_MULTIPLE_INSTANCES wasn't anywhere near mandatory all that time...
Kernel upgrade procedure that starts with "build the old kernel with
that option enabled, boot it, replace /dev/ptmx with a symlink, then
never try to boot earlier kernel images. Now you can safely upgrade
to current kernel" is the recipe for massive self-LARTs (and resulting
pitchfork crowds).
