They are in the same directory.  Remember that when you pass mkisofs a
list of directories, their contents are combined to create the CD.  you
can't have duplicates, though. /disk2/larry/CUSTOM and
/disk2/curly/CUSTOM both map to "/CUSTOM" on the cdrom. If you really
wanted the cdrom to contain two subdirectories named "/larry" and
"/curly", try passing just "/disk2" to mkisofs, or if there are other
directories in disk2, create a /disk2/cdrom, move larry and curly into
there, and run "mkisofs /disk2/cdrom".
