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. AUTHOR

NAME
cback-span - Span staged data among multiple discs SYNOPSIS
cback-span [switches] DESCRIPTION
This is the Cedar Backup span tool. It is intended for use by people who back up more data than can fit on a single disc. It allows a user to split (span) staged data between more than one disc. It can't be a Cedar Backup extension in the usual sense because it requires user input when switching media. Generally, one can run the cback-span command with no arguments. This will start it using the default configuration file, the default log file, etc. You only need to use the switches if you need to change the default behavior. This command takes most of its configuration from the Cedar Backup configuration file, specifically the store section. Then, more informa- tion is gathered from the user interactively while the command is running. SWITCHES
-h, --help Display usage/help listing. -V, --version Display version information. -b, --verbose Print verbose output to the screen as well writing to the logfile. When this option is enabled, most information that would normally be written to the logfile will also be written to the screen. -c, --config Specify the path to an alternate configuration file. The default configuration file is /etc/cback.conf. -l, --logfile Specify the path to an alternate logfile. The default logfile file is /var/log/cback.log. -o, --owner Specify the ownership of the logfile, in the form user:group. The default ownership is root:adm, to match the Debian standard for most logfiles. This value will only be used when creating a new logfile. If the logfile already exists when the cback script is executed, it will retain its existing ownership and mode. Only user and group names may be used, not numeric uid and gid values. -m, --mode Specify the permissions for the logfile, using the numeric mode as in chmod(1). The default mode is 640 (-rw-r-----). This value will only be used when creating a new logfile. If the logfile already exists when the cback script is executed, it will retain its existing ownership and mode. -O, --output Record some sub-command output to the logfile. When this option is enabled, all output from system commands will be logged. This might be useful for debugging or just for reference. Cedar Backup uses system commands mostly for dealing with the CD recorder and its media. -d, --debug Write debugging information to the logfile. This option produces a high volume of output, and would generally only be needed when debugging a problem. This option implies the --output option, as well. -s, --stack Dump a Python stack trace instead of swallowing exceptions. This forces Cedar Backup to dump the entire Python stack trace associ- ated with an error, rather than just progating last message it received back up to the user interface. Under some circumstances, this is useful information to include along with a bug report. RETURN VALUES
This command returns 0 (zero) upon normal completion, and six other error codes related to particular errors. 1 The Python interpreter version is < 2.5. 2 Error processing command-line arguments. 3 Error configuring logging. 4 Error parsing indicated configuration file. 5 Backup was interrupted with a CTRL-C or similar. 6 Other error during processing. NOTES
Cedar Backup itself is designed to run as root, since otherwise it's difficult to back up system directories or write the CD or DVD device. However, this command can be run safely as any user that has read access to the Cedar Backup staging directories and write access to the CD or DVD device. SEE ALSO
