Hi,
We found out that it's not possible to create UDF images with hidden files
using mkisofs, though UDF specification supports this feature. The patch below
adds support into mkisofs (v3.02a09). May the patch be considered to be added
to (hopefully) upcoming version?

Subject: [PATCH] Support setting 'hidden' FileCharacteristic in UDF
Options '-hidden' and '-hidden-list' work for UDF images the same
way as for IS09660.
