# Maximum time, in seconds, of hard drive spindown time that you are
# confortable with. Worst case, it's possible that you could lose this
# amount of work if your battery fails you while in laptop mode.
#MAX_AGE=600

# Read-ahead, in 512-byte sectors. You can spin down the disk while playing MP3/OGG
# by setting the disk readahead to 8MB (READAHEAD=16384). Effectively, the disk
# will read a complete MP3 at once, and will then spin down while the MP3/OGG is
# playing.
#READAHEAD=4096

# Shall we remount journaled fs. with appropiate commit interval? (1=yes)
#DO_REMOUNTS=1

# And shall we add the "noatime" option to that as well? (1=yes)
#DO_REMOUNT_NOATIME=1

# Dirty synchronous ratio.  At this percentage of dirty pages the process
# which calls write() does its own writeback
#DIRTY_RATIO=40

#
# Allowed dirty background ratio, in percent.  Once DIRTY_RATIO has been
# exceeded, the kernel will wake pdflush which will then reduce the amount
# of dirty memory to dirty_background_ratio.  Set this nice and low, so once
# some writeout has commenced, we do a lot of it.

# This must be adjusted manually to the value of HZ in the running kernel
# on 2.4, until the XFS people change their 2.4 external interfaces to work in
# centisecs. This can be automated, but it's a work in progress that still
# needs# some fixes. On 2.6 kernels, XFS uses USER_HZ instead of HZ for
# external interfaces, and that is currently always set to 100. So you don't
# need to change this on 2.6.
#XFS_HZ=100

# Should the maximum CPU frequency be adjusted down while on battery?
# Requires CPUFreq to be setup.
# See Documentation/cpu-freq/user-guide.txt for more info
#DO_CPU=0

# When on battery what is the maximum CPU speed that the system should
# use? Legal values are "slowest" for the slowest speed that your
# CPU is able to operate at, or a value listed in:
# /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
# Only applicable if DO_CPU=1.
#CPU_MAXFREQ=slowest

# Idle timeout for your hard drive (man hdparm for valid values, -S option)
# Default is 2 hours on AC (AC_HD=244) and 20 seconds for battery (BATT_HD=4).
#AC_HD=244
#BATT_HD=4

# The drives for which to adjust the idle timeout. Separate them by a space,
# e.g. HD="/dev/hda /dev/hdb".
#HD="/dev/hda"

# Set the spindown timeout on a hard drive?
