It's not that easy. Case sensitivity is a property of a file system, not of the operating system. So if you mount a Windows or Mac OS volume on a Linux system, the filenames on that volume will still be case-insensitive (but case-preserving). On Mac OS X, the default file system type is HFS+ (a.k.a. Mac OS Extended), which is case insensitive, but you can also choose UFS (case sensitive). You could also have both, on two partitions. Of course, "False" for Windows and MacOS, "True" for everything else is a reasonable guess, but you can't rely on it. Right now I have no idea how to implement something like
isCaseSensitive :: FilePath -> IO Bool
See 'statfs(2)' and 'fstatfs(2)', there should be enough info there to implement it. plus an interface to the other information returned by these functions would be useful. perhaps we need a standard trinary data type, True,False,Unknown. I guess (Maybe Bool) works.
