It's a driver settings string in flat format.
It could look like this:
"key1 = value; key2 = value"
or:
"key1 value; key2 value"
or:
"key1 = value { key2 = value; key3 = value }"

Depending on if the settings are nested or not. For a file system, they 
probably aren't ever nested, though.

You don't have to. You will just get this string from the command line, 
and pass it over to the initialize function unchanged.
Every file system will have different options, so you cannot make any 
assumptions on what the file system needs here. While we could try to 
specify some generic options that all file systems may want to support 
(if applicable), we haven't done so yet.

Bye,
