According to chkudf tool (present on linux udf 0.9.0), it is possible
that mkisofs is not generating compliant volumes. Please check this

--Testing link counts.
  There are 3 directories and 6 files.

  0 FIDs had a wrong location value.

--Checking Unique ID list.
  The maximum Unique ID is 131125.
**The Integrity Descriptor indicated a maximum Unique ID of 270.

I can note that the following

**(R) Volume Set ID:     '55D5E6BD0000545A'

does not appear with a compliant volume.

Thanks for your attention.
