hrmmm OK, thanks, sorry for teh noise, I'll have to investigate why
current man pages are not installed, since I have man page saying
-iso-level level
Set the iso9660 conformance level. Valid numbers are 1..3 and 4.
With level 1, files may only consist of one section and filenames
are restricted to 8.3 characters.
With level 2, files may only consist of one section.
With level 3, no restrictions (other than ISO-9660:1988) do apply.
With all iso9660 levels from 1..3, all filenames are restricted to
upper case letters, numbers and the underscore (_). The maximum filename
length is restricted to 31 characters, the directory nesting level is
restricted to 8 and the maximum path length is limited to 255
characters.
Level 4 officially does not exists but mkisofs maps it to
ISO-9660:1999 which is ISO-9660 version 2.
With level 4, an enhanced volume descriptor with version number and
file structure version number set to 2 is emitted. There may be more
than 8 levels of directory nesting, there is no need for a file to
contain a dot and the dot has no more special meaning, file names do not
have version numbers, the maximum length for files and directory is
raised to 207. If Rock Ridge is used, the maximum ISO-9660 name length
is reduced to 197.
When creating Version 2 images, mkisofs emits an enhanced volume
descriptor which looks similar to a primary volume descriptor but is
slightly different. Be careful not to use broken software to make
ISO-9660 images bootable by assuming a second PVD copy and patching this
putative PVD copy into an El Torito VD.
...... which obviously differs from what you show...
Cheers
