>Description:
While going through the makefs cd9660 options for bin/50390 further, I noticed that the following options are implemented as available options, but aren't implement in the underlying code:

- allow-illegal-chars
- allow-lowercase
- bootimagedir
- follow-symlinks

Each of these options break the ISO-9660 standard to some degree (the Joliot/Rock ridge extensions unlock a number of other features that the original standard didn't allow). I'm not sure if it's a good idea to allow these options to exist as it gives the user the expectation that these options do something, when in reality they don't do anything.
