Mk9660 writes to the random access file
image an ISO-9660 CD image containing the
files named in
proto (by default,
/usr/local/plan9/proto/allproto) from the file tree
src (by default,
the current directory).
proto file is formatted as described in
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.
-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
Dnnnnnn (for directories)
Fnnnnnn (for files);
a key file
_CONFORM.MAP is created in the root
directory to ease the reverse process.
-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
-j flag is given, the usual directory tree is written,
but an additional tree in Microsoft Joliet format is
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.
\ are allowed in Plan 9 file names but not in Joliet file names;
non-conforming file names are translated
_CONFORM.MAP file written
as in the case of 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.
-r may be mixed freely with the exception that
-r are mutually exclusive.
-v flag sets the volume title;
if unspecified, the base name of
proto is used.
-: flag causes
mk9660 to replace colons in scanned file names with spaces;
this is the inverse of the map applied by Plan 9s
and is useful for writing Joliet CDs containing data
from FAT file systems.
-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:
-b flag just creates a pointer to it.
-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
dump file system
(see Plan 9s fs(4)).
The dump is file-based rather than block-based:
if a files contents have not changed since the last
backup, only its directory entry will be rewritten.
-n option specifies a time (in seconds since January 1, 1970)
to be used for naming the dump directory.
-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.
