CD-ROM (ISO9660) filesystem
The limits for CD-ROM (ISO9660) filesystems include:
- Filename length
- 32 bytes for basic ISO9660, 128 for Joliet, 255 for Rockridge.
- Pathname length
- 1024 bytes.
- Disk size
- This filesystem also uses a 32-bit (4 GB − 1) format. We don't allow the creation of anything via fs-cd.so; it's read-only. Any limits would be imposed by the tools used to make the image (which hopefully would be a subset of ISO9660). Disk size is also limited by the disk driver and io-blk.
