# Udev rules for Archlinux by Tobias Powalowski <tpowa@archlinux.org>
#
# This ruleset should provide a DevFS-compatible device tree.
#
# 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
# %s{filename} the content of a sysfs attribute.
# %% the '%' char itself.
#
# There are a number of modifiers that are allowed to be used in some of the
# fields.  See the udev man page for a full description of them.
