from the man page of mkisofs it appears that mkisofs can detect 
hardlinks and realizes space savings based on these:

-cache-inodes               Cache inode and device numbers to find hard 
links to files.  If mkisofs finds a hard link (a file with multiple 
names), then the file will only appear once on the CD. This helps to 
save space on the CD.  The option -cache-inodes  is default on UNIX like 
operating systems.  Be careful when using this option on a filesystem 
without unique inode numbers as it may result in files containing the 
wrong content on CD.
