Had our esteemed moderator tested this hint, he would have found it doesn't work as described. System/Library/Core Services is only writable by the user when preceded by "sudo". Thus, the correct syntax should be

 sudo cp -R /Volumes/[your disk's name]/System/Library/CoreServices/.diagnostics /System/Library/CoreServices

Doh!

Yeah, you're quite correct! Sorry for the mistake.

Somehow I forgot to add that in when writing the hint (or I was using the root account at the time….)

Anyway, yes, sudo must be used. (It would be nice if the original hint could be modified. :))

Doh!

Had out esteemed smarta$$ looked, he'd have seen that Baltutis below posted the correct command.

If you're gonna call someone out, be smarter.

sudo cp -R /Volumes/[your INSTALL DISK name]/System/Library/CoreServices/.diagnostics /System/Library/CoreServices
