I don't know the answer to the following question, which is why I ask it:
does that happen if you use 9660srv
under Plan 9 (-ish) to access those images? (Perhaps you already are, but
it would still be useful to know.)
It's quite a long time ago, but as I recall early CD formats took a literal
view of permissions: "I'm on a read-only medium,
otherwise you'd be using the later and probably incompatible standard for
RW optical, so all my file system permissions are "read".
Later people took advantage of having umptieen parallel trees in there in
different formats (Joliet for MS, High Sierra for UNIX-ish)
and Plan 9 added its own. I think those early CDs relied on that. Later
ones added parallel structures in both Joliet and High Sierra
format so you could get more accurate meta-date out of the CDs when mounted
on Windows or SunOS.
