@kindex -rational-rock Rock Ridge with altered owner and permission
Alias of -r.
@c man .TP
@item -D
@kindex -D allow deep directory hierachies
@cindex Deep directories, allow, -D, -disable-deep-relocation
The standard ECMA-119 demands that no path in the image shall have more
than 8 name components. Therefore it would be necessary to move deeper
directory trees to a higher directory. Rock Ridge offers an opportunity to
let these relocated directories appear at their orginal deep position, but
this feature might not be implemented properly by operating systems which
mount the image.
@*
Option -D disables this deep directory relocation, and thus violates
ISO 9660 specs.
@*
xorrisofs has -D set by default. It may get overridden by option -rr_reloc_dir
or by option -hide-rr-moved, and it may override said options. The last one
in the option list wins.
@c man .TP
@item -disable-deep-relocation
@kindex -disable-deep-relocation allow deep directory hierachies
Alias of -D.
@c man .TP
@item -rr_reloc_dir name
@kindex -rr_reloc_dir set deep directory relocation target
@cindex Deep directories, relocation target, -rr_reloc_dir
Enable the relocation of deep directories and thus avoid ECMA-119 file paths
of more than 8 name components. Directories of depth 8 will get moved to a
directory in the root directory of the image. Its name gets set by this option.
It is permissible to use the root directory itself.
@*
The overall directory tree will appear originally deep when interpreted as
Rock Ridge tree. It will appear as re-arranged if only ECMA-119 information
is considered.
@*
If the given relocation target directory does not already exist when image
production begins, then it will get created and marked for Rock Ridge as
relocation artefact. At least on GNU/Linux it will not be displayed in
mounted Rock Ridge images.
@*
The name must not contain a '/' character after its first character and it
must not be longer than 255 bytes.
