Eh, note that find does special optimization which does not work on CD ROM's. It assumes that two directories are "." and "..". From the info page: - Option: -noleaf Do not optimize by assuming that directories contain 2 fewer subdirectories than their hard link count. This option is needed when searching filesystems that do not follow the Unix directory-link convention, such as CD-ROM or MS-DOS filesystems or AFS volume mount points. Each directory on a normal Unix filesystem has at least 2 hard links: its name and its `.' entry. Additionally, its subdirectories (if any) each have a `..' entry linked to that directory. When `find' is examining a directory, after it has statted 2 fewer subdirectories than the directory's link count, it knows that the rest of the entries in the directory are non-directories ("leaf" files in the directory tree). If only the files' names need to be examined, there is no need to stat them; this gives a significant increase in search speed. -- `Rhubarb is no Egyptian god.'
