SH DESCRIPTION
I Mk9660
writes to the random access file
I image
an ISO-9660 CD image containing the
files named in
I proto
(default
BR /sys/lib/sysconfig/proto/allproto )
from the file tree
I src
(default
BR / ).
The
I proto
file is formatted as described in
IR mkfs (8).
PP
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
B -c
flag causes
I 9660srv
to use only file names in ``8.3'' form
that use digits, letters, and underscore.
File names that do not conform are changed
to
BI D nnnnnn
(for directories)
or
BI F nnnnnn
(for files);
a key file
B _CONFORM.MAP
is created in the root
directory to ease the reverse process.
PP
If the
B -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
IR 9660srv .
PP
If the
B -j
flag is given, the usual directory tree is written,
but an additional tree in Microsoft Joliet format is
alos added.
This second tree can contain long Unicode file names,
and can be read by
I 9660srv
as well as most versions of Windows
and many Unix clones.
The characters
BR * ,
BR : ,
BR ; ,
BR ? ,
and
B \e
are allowed in Plan 9 file names but not in Joliet file names;
non-conforming file names are translated
and a
B _CONFORM.MAP
file written
as in the case of the
B -c
option.
PP
If the
B -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.
PP
The options
BR -c ,
BR -9 ,
BR -j ,
and
B -r
may be mixed freely with the exception that
B -9
and
B -r
are mutually exclusive.
PP
The
B -v
flag sets the volume title;
if unspecified, the base name of
I proto
is used.
PP
The
B -:
flag causes
B mk9660
to replace colons in scanned filenames with spaces;
this is the inverse of the map applied by
IR dossrv (4)
and is useful for writing Joliet CDs containing data
from FAT file systems.
PP
The
B -D
flag creates immense amounts of debugging output
on standard error.
PP
I Dump9660
is similar in specification to
I mk9660
but creates and updates backup CD images in the style of
the
I dump
file system
(see
IR 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.
PP
The
B -n
option specifies a time (in seconds since January 1, 1970)
to be used for naming the dump directory.
PP
The
B -m
option specifies a maximum size for the image;
if a backup would cause the image to grow larger than
IR maxsize ,
it will not be written, and
I dump9660
will exit with a non-empty status.
SH EXAMPLE
PP
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.
