Well we all do stupid things sometimes... 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.
