He was in panic mode and planning to take down the server to boot from the installation CD in order to fix it. That would have resulted in a few hundred people unable to work for a while. I had the idea of writing a quick program on another workstation and copying that to an NFS share that was mounted by that server. The program would copy 'ldd' from another disk to '/bin/ldd' but the catch was that it could not load any system libraries, it had to be static linked with the correct version of each library it required. The bigger catch was that I had a deadline of under 5 minutes to get it working.
