Restore -i is pretty cute, particularly as our users rarely know the complete path name of a file accurately, and dump is faster ... What does cpio do if it receives a name from find that has just been removed? How about directories? Do you have to read the entire cpio file to know if a file is on it (assuming no TOC held on a disk)? Does -newer just check the modification time, if so you might miss some files that have been touched backwards, it should use the inode change time.
