Besides such user pitfalls with the produced ISO and the problem of
symbolic links there are other constraints which an ISO has to fulfill
for this use case.
At least:
- The file tree of the FAT filesystem in the EFI partition needs to be
  mirrored by a copy in the ISO filesystem.
- File names must be unique in respect to case-insensitive comparison.
- (I am not sure whether file name length can be a problem.)

I guess Pete Batard can give a more comprehensive list.


Have a nice day :)
