2    What is UMSDOS                                              

    UMSDOS stand for "Unix in MSDOS" file system. UMSDOS is a 
    full feature unixlike file system for LINUX. It operates 
    within the limits (and semantics) of a normal MSDOS FAT file 
    system. chkdsk won't complain at all. No dirty tricks. 
    UMSDOS DOES not use MSDOS (the OS) to run. In case anyone 
    wonder. Using a special file in each directory 
    ("--linux-.---"), UMSDOS simulate the full UNIX semantic (I 
    hope :-) ):

        Long file name
            case sensitive
            free format file name like "This.is.a.sample"
        Permissions and owner (user and group)
        Links (hard and symbolic)
        Device special and pipe

    UMSDOS is powerful enough to act as a ROOT file system for 
    LINUX. From a Linux kernel standpoint, this is a true 
    filesystem. Compile a kernel with UMSDOS, put it on a 
    disquette, use rdev to specify the proper root partition 
    (Any msdos partition with linux in it), and boot. In the 
    following document, the --linux-.--- will be named EMD 
    (Extension to Msdos Directory).
