The limits for UDF filesystems include:
- Filename length
- 255 Unicode characters.
- Pathname length
- 1024 bytes, not including the mountpoint or the terminating NUL.
- Disk size
- This filesystem uses a 32-bit block address, but the filesystem is
  64-bit (> 4 GB).
  We don't allow the creation of anything via fs-udf.so;
  it's read-only.
