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.
16 #
17 # Try not to modify this file, if you wish to change things, create a new rule
18 # file that can be run before this one.
