Question: Does the CD-ROM file system look exactly like an AmigaDOS file
system, or is it just somewhat compatible?

After seeing how Sun is distributing SunOS-4.1 on CD-ROM, I get the impression
that the standard for CD-ROMs have a different limitation in the length of
a file name, have a more restricted set of characters allowed in a file name,
and have a limitation on the number of periods in a file name.  Also, the
standard format of CD-ROM for MS-DOS and Macintosh don't handle Unix
protection bits, much less the AmigaDOS protection bits.

In other words, to store the contents of an entire Amiga floppy on CD-ROM and
preserve all the AmigaDOS attibutes requires using something like ZOO or
LHARC.  Not all of the files in the current Fred Fish collection could be
stored on CD-ROM as simple files because some of the file names have illegal
characters.

Could someone please post an overview of the current CD-ROM standards?
At least, outline the differences between the High Sierra File System and
AmigaDOS.
