+# /etc/sysfs.conf - Configuration file for setting sysfs attributes.
+#
+# The sysfs mount directory is automatically prepended to the attribute paths.
+#
+# Syntax:
+# attribute = value
+# mode attribute = 0600 # (any valid argument for chmod)
+# owner attribute = root:wheel # (any valid argument for chown)
+#
+# Examples:
+#
+# Always use the powersave CPU frequency governor
+# devices/system/cpu/cpu0/cpufreq/scaling_governor = powersave
+#
+# Use userspace CPU frequency governor and set initial speed
+# devices/system/cpu/cpu0/cpufreq/scaling_governor = userspace
+# devices/system/cpu/cpu0/cpufreq/scaling_setspeed = 600000
+#
+# Set permissions of suspend control file
