It's anso case-insensitive which may cause some further troubles. It's
doesn't have proper inodes, no UNIX file modes, no UID / GID support (These
two can be kludges in awfully insufficient way through mount options), not
only lacks device special files but also no FIFO, no UNIX domain sockets,
no hard or soft links. It's simply a sorry excuse for a useful filesystem.
