Hard links are part of the Rock Ridge standard. Did you ever test
your hardlinks (on a OS that suppots hard links) for correctness?
Just as a note: Linux does not support hard links on ISO-9660.

Also please admit that there is no standard for ACLs or xattrs for ISO-9660.

What you implement may be a nice toy but it is irrelevent for real world
usage. What you implement is your private nonstandard proprietary 
extension  on ISO-9660 that is based on the data structures of a 
POSIX _draft_ that was withdrawn 10 years ago in 1999 and thus never was a 
standard. It is not complatible to the ACL and xattr standard that is 
implemented on many recent OS and that is described here:


See page 50 ff and page 178.

Mkisofs does not have a -md5 option.

In case that mkisofs will eventually add a -md5 option, I cannot grant that 
this option will be compatible to what you implement.....
