There are lot of options for writing scripts to do this, but an appropriate
place to start looking for solutions is in the origin of the problem: how
the filesystem is mounted.  Take a look at the man page for mount(8).

You'll see that you can

mount -t iso9660 -o check=relaxed /dev/cdrom /mnt/cdrom

Look around further in mount(8) and you'll see other information relevant
to how filesystems are interpreted upon being mounted.

Here's your script, incidentally: run these two "find" commands.

PREFIX=/cool-place
find /source -type d -exec withlcase $PREFIX/'{}' mkdir -p \;
find /source -type f -exec withlcase $PREFIX/'{}' cp '{}' \;

The "withlcase" script is:


#!/bin/sh
# withlcase: execute $2, ... with lowercase($1) as argument

FILE=`echo "$1" | tr [A-Z] [a-z]`
shift
$* $FILE


This does work (in my little test), but should be unnecessary.  You get a
/cool-place/source tree containing the original /source, but with lower-case
filenames.  (There are some problems, like if two file have the same name,
or if there were symlinks in the original, but for your situation, this
should also work.)
