    4    # There are a number of modifiers that are allowed to be used in some
    5    # of the different fields. They provide the following subsitutions:
    6    # %n - the "kernel number" of the device.
    7    #      For example, 'sda3' has a "kernel number" of '3'
    8    # %k - the kernel name for the device.
    9    # %M - the kernel major number for the device
    10    # %m - the kernel minor number for the device
    11    # %b - the bus id for the device
    12    # %c - the string returned by the PROGRAM. (Note, this doesn't work within
    13    #      the PROGRAM field for the obvious reason.)
    14    # %s{filename} - the content of a sysfs attribute.
    15    # %% - the '%' char itself.
