Comment 1 for bug 959724

So, doing the grep as you suggest gives me these supportable filesystems:

    'btrfs',
    'ext2',
    'fat',
    'hfsplus',
    'nilfs2',
    'ntfs',

so I think you have to special case (i.e. manually add to the list) ext3 and ext4 also, and probably fat16 and fat32 too. Am I missing something?
