That is, it is first installed to a temporary file, and then it is atomically renamed to ld-elf.so.1. It ensures that at all times there is a valid dynamic linker, even if you kill the job in the middle of the install. You _really_ don't want to have a system with a corrupted or missing dynamic linker. John -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
