If you plan on using union mounts, then you should consider replacing three files in "libc/gen" in the C library with the files in "libc" in this directory. The replacement version of opendir() automatically removes duplicate names when a union stack is encountered. The other two files do special handling of whiteouts. You will then need to rebuild the C library and all commands. @(#)README 8.2 (Berkeley) 11/4/94
