While I like to see Multiboot support coming, I don't think that using
optstr (or any other text-based mechanism) for mount(2) is a good idea.
Text-based formats have the disadvantage of not allowing some arbitrary
characters (in this case, spaces), without some quoting mechanism which
would complicate it. Space is not an unreasonable character in a mount
option...
