       dump9660, mk9660 - create an ISO-9660 CD image

       disk/mk9660 [ -:D ] [ -9cjr ] [ -b bootfile ] [ -B bootfile [ -x loader
       ] ] [ -p proto ] [ -s src ] [ -v volume ] image

       disk/dump9660 [ -:D ] [ -9cjr ] [ -p proto ] [ -s src ] [ -v volume ] [
       -m maxsize ] [ -n now ] image

       Mk9660 writes to the random access file image an ISO-9660 CD image con‐
       taining	the  files  named  in  proto  (by  default,   /sys/lib/syscon‐
       fig/proto/portproto)  from  the	file tree src (by default, the current
       directory).  The proto file is formatted as described in mkfs(8).

       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  for‐
       mat  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 dossrv(4) and is use‐
       ful 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 option just creates a pointer to it.

       The -B option is similar to -b but the created CD image	is  marked  as
       having  a  non-floppy-emulation	boot block.  This gives the program in
       the boot block full (ATA) LBA access to the CD filesystem, not just the
       initial	blocks	that  would  fit on a floppy.  Additionally, -x can be
       used in conjunction with -B to make mk9660 annotate the boot file  with
       the  address and size of the loader, which has to be a file in the CD's
       root directory.

       The -D flag creates immense amounts of  debugging  output  on  standard

       Dump9660	 is similar in specification to mk9660 but creates and updates
       backup CD images in the style of the dump file system (see 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

       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.

       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.
