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.
Note:
We've deprecated
fs-cd.so in favor of
fs-udf.so,
which now supports ISO-9660 filesystems in addition to UDF.
For information about the limits for UDF, see
"UDF filesystem,"
later in this chapter.
