1If you plan on using union mounts, then you should consider replacing 2three files in "libc/gen" in the C library with the files in "libc" 3in this directory. The replacement version of opendir() automatically 4removes duplicate names when a union stack is encountered. The other 5two files do special handling of whiteouts. You will then need to 6rebuild the C library and all commands. 7 8@(#)README 8.2 (Berkeley) 11/04/94 9
