Not quite. According to mkisofs(1):
-l Allow full 32 character filenames. Normally the
ISO9660 filename will be in an 8.3 format which is
compatible with MS-DOS, even though the ISO9660
standard allows filenames of up to 32 characters.
If you use this option, the disc may be difficult
to use on a MS-DOS system, but this comes in handy
on some other systems (such as the Amiga). Use
with caution.
It's depressing to see just how long the legacy of MS-DOS persists. :-(
The ISO9660 format supports 32 chars, but since nearly everything uses 8.3
to be readable by MSCDEX and windoze, the 32 character names are rarely
implemented or well tested.
