Cool idea.  I didn't do that -- didn't think of it, and also because I
didn't know enough 9660 then.

No, RSTS is RDS-1; it's a file structure all its own, totally
unrelated to any other PDP-11 OS.  (It's a distant relative of the
TSS-8 file system, though.)

In particular, the naming aspects (directory) and file block to disk
block mapping aspects (file header in ODS, inode in Unix) are combined
in the RSTS directory structure, unfortunately.  So there is no rename
across directories and neither softlinks nor hardlinks.

It's all nicely documented in the RSTS internals manuals, and you can
also read all about it in the RSTSFLX sources.
