As William correctly guessed, the CD image has
ISO9660, Plan 9, and Joliet (MS Windows Unicode
long names) file tables.  No Rock Ridge, because
Plan 9 and Rock Ridge are somewhat incompatible.

You're seeing the Joliet names, or else you'd
see a lot more [DF]xxxxxx names.  The ones in
/rc/bin are unfortunate: even in Joliet they
have to be rewritten since they contain reserved
characters (the colons).

There's no way around this unless you implement
the Plan 9 extensions in your iso9660 reader.

(I could try to make Plan 9 and Rock Ridge extensions coexist,
but I'm really quite happy with Joliet, which has
the advantage of having a clear definition for dealing
with Unicode.)
