# There are a number of modifiers that are allowed to be used in some
# of the different fields. They provide the following subsitutions:
# %n - the "kernel number" of the device.
#      For example, 'sda3' has a "kernel number" of '3'
# %k - the kernel name for the device.
# %M - the kernel major number for the device
# %m - the kernel minor number for the device
# %b - the bus id for the device
# %c - the string returned by the PROGRAM. (Note, this doesn't work within
#      the PROGRAM field for the obvious reason.)
# %s{filename} - the content of a sysfs attribute.
# %% - the '%' char itself.
#
# Try not to modify this file, if you wish to change things, create a new rule
# file that can be run before this one.
