HDAPSD(8) hdapsd HDAPSD(8)NAME
hdapsd - park the drive in case of an emergency
SYNOPSIS
hdapsd [-f|-d <device>|-s <sensitivity>|-a|-v|-b|-p|-t|-y|-l|-V|-h]
OPTIONS -d --device=<device>
<device> is likely to be hda or sda. Can be given multiple times to protect multiple devices.
-f --force
Force unloading heads, even if kernel thinks different (on pre ATA7 drives). This only works when adding devices by hand (-d).
-s --sensitivity=<sensitivity>
How sensitive hdapsd should be to movements. Defaults to 15, higher values mean less sensitive.
-a --adaptive
Adaptive threshold (automatic increase when the built-in keyboard/mouse are used).
-v --verbose
Get verbose statistics.
-b --background
Run the process in the background.
-p --pidfile[=<pidfile>]
Create a pid file when running in background. If <pidfile> is not specified, it's set to /var/run/hdapsd.pid.
-t --dry-run
Don't actually park the drive.
-y --poll-sysfs
Force use of sysfs interface to accelerometer.
-l --syslog
Log to syslog instead of stdout/stderr.
-V --version
Display version information and exit.
-h --help
Display help and exit.
You can send SIGUSR1 to deactivate hdapsd for 8 seconds.

BOOTLOGD(8) Linux System Administrator's Manual BOOTLOGD(8)NAME
bootlogd - record boot messages
SYNOPSIS
/sbin/bootlogd [-c] [-d] [-r] [-s] [-v] [ -l logfile ] [ -p pidfile ]
DESCRIPTION
Bootlogd runs in the background and copies all strings sent to the /dev/console device to a logfile. If the logfile is not accessible, the
messages will be kept in memory until it is.
OPTIONS -d Do not fork and run in the background.
-c Attempt to write to the logfile even if it does not yet exist. Without this option, bootlogd will wait for the logfile to appear
before attempting to write to it. This behavior prevents bootlogd from creating logfiles under mount points.
-r If there is an existing logfile called logfile rename it to logfile~ unless logfile~ already exists.
-s Ensure that the data is written to the file after each line by calling fdatasync(3). This will slow down a fsck(8) process running
in parallel.
-v Show version.
-l logfile
Log to this logfile. The default is /var/log/boot.
-p pidfile
Put process-id in this file. The default is no pidfile.
BUGS
Bootlogd works by redirecting the console output from the console device. (Consequently bootlogd requires PTY support in the kernel con-
figuration.) It copies that output to the real console device and to a log file. There is no standard way of ascertaining the real con-
sole device if you have a new-style /dev/console device (major 5, minor 1) so bootlogd parses the kernel command line looking for con-
sole=... lines and deduces the real console device from that. If that syntax is ever changed by the kernel, or a console type is used that
bootlogd does not know about then bootlogd will not work.
