 DESCRIPTION     
 |  |  |  | Mk9660 writes to the random access file image an ISO-9660 CD image
    containing the files named in proto (by default, /usr/lib/plan9/proto/allproto)
    from the file tree src (by default, the current directory). The
    proto file is formatted as described in proto(3). 
    
    
    The created CD image will be in ISO-9660 format, but by default
    the file names will be stored in UTF-8 with no imposed length
    or character restrictions. The −c flag causes mk9660 to use only
    file names in “8.3” form that use digits, letters, and underscore.
    File names that do not conform are changed to Dnnnnnn (for directories)
    or Fnnnnnn (for files); a
    key file _CONFORM.MAP is created in the root directory to ease
    the reverse process. 
    
    
    If the −9 flag is given, the system use fields at the end of each
    directory entry will be populated with Plan directory information
    (owner, group, mode, full name); this is interpreted by 9660srv.
    
    
    
    If the −j flag is given, the usual directory tree is written,
    but an additional tree in Microsoft Joliet format is also added.
    This second tree can contain long Unicode file names, and can
    be read by 9660srv as well as most versions of Windows and many
    Unix clones. The characters *, :, ;, ?, and \ are allowed in Plan
    9 file names but not in Joliet file
    names; non-conforming file names are translated and a _CONFORM.MAP
    file written as in the case of the −c option. 
    
    
    If the −r flag is given, Rock Ridge extensions are written in
    the format of the system use sharing protocol; this format provides
    Posix-style file metadata and is common on Unix platforms. 
    
    
    The options −c, −9, −j, and −r may be mixed freely with the exception
    that −9 and −r are mutually exclusive. 
    
    
    The −v flag sets the volume title; if unspecified, the base name
    of proto is used. 
    
    
    The −: flag causes mk9660 to replace colons in scanned file names
    with spaces; this is the inverse of the map applied by Plan 9’s
    dossrv(4) and is useful for writing Joliet CDs containing data
    from FAT file systems. 
    
    
    The −b option creates a bootable CD. Bootable CDs contain pointers
    to floppy images which are loaded and booted by the BIOS. Bootfile
    should be the name of the floppy image to use; it is a path relative
    to the root of the created CD. That is, the boot floppy image
    must be listed in the proto file already: the −b flag just creates
    a pointer to it. 
    
    
    The −D flag creates immense amounts of debugging output on standard
    error. 
    
    
    Dump9660 is similar in specification to mk9660 but creates and
    updates backup CD images in the style of the dump file system
    (see Plan 9’s fs(4)). The dump is file-based rather than block-based:
    if a file’s contents have not changed since the last backup, only
    its directory entry will be rewritten. 
    
    
    The −n option specifies a time (in seconds since January 1, 1970)
    to be used for naming the dump directory. 
    
    
    The −m option specifies a maximum size for the image; if a backup
    would cause the image to grow larger than maxsize, it will not
    be written, and dump9660 will exit with a non-empty status.

 EXAMPLE     
 |  |  |  | Create an image of the Plan 9 source tree, including a conformant
    ISO-9660 directory tree, Plan 9 extensions in the system use fields,
    and a Joliet directory tree.
