I done similar to you once, but copied (and overwrote) a different version trying to fix something... /sbin/sln is your friend (if you don't panic when it happens). No need for a large vfs to monitor user errors like this. /sbin/sln is a statically built ln, so you can symlink back the file to get userspace going, then copy the file (fix it) back properly.
