Yeah, I theory.

But that part of FHS, specifying enumerated directories there is one
of the most silly parts of FHS:
  "The following directories _must_ be in /media: floppy, cdrom,
cdrecorder, zip."

I would not read too much into it, it just does not make much sense at
all; somebody was clearly completely confused when writing that. :)

Yeah, we should leave it alone. And if people want that 'zip' and
'floppy' directories, they should be happy. :)
