udev.rules

在Linux2.6内核下的udev文件系统的源码

# /etc/udev/udev.rules:  device naming rules for udev
#
# 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.

# This rules file is a mix of 10.2 Slackware udev.rules file and some
# rules from the udev examples.
