>
>## Type:	string
>## Default:	"kdump"
>## ServiceRestart:	kdump
>#
># Kernel Version string for the -kdump kernel, such as 2.6.16-5-kdump
># If no version is specified, then the init script will try to find a
># kdump kernel with the same version number as the running kernel.
># The init script will use a kernel named:
># /boot/vmlinux-$KDUMP_KERNELVER
># Using "kdump" will default to the most recently installed kdump kernel.
>#
>KDUMP_KERNELVER=""
>
>## Type:	string
>## Default:	""
>## ServiceRestart:	kdump
>#
># The kdump commandline is the command line that needs to be passed off to
># the kdump kernel.  This will likely match the contents of the grub kernel
># line.  For example:
>#   KDUMP_COMMANDLINE="ro root=LABEL=/"
># If a command line is not specified, the default will be taken from
># /proc/cmdline
>#
>KDUMP_COMMANDLINE=""
>
>## Type:        string
>## Default:     ""
>## ServiceRestart:     kdump

>KDUMP_COMMANDLINE_APPEND="maxcpus=1 "

>## Type:	string

># A script or command executed to process and transfer the dump image.

>## Type:	string
>## Default:	"file:///var/log/dump"
>#
># Which directory should the dumps be saved in by the default dumper?
># This can be:
>#
>#   - a local file, for example "file:///var/log/dump" (or, deprecated,
>#     just "/var/log/dump")
>#   - a FTP server, for example "ftp://user:password@host/var/log/dump"
>#   - a SSH server, for example "ssh://user@host/var/log/dump"
>#     please create a user that needs no password or set up public key
>#     authorization for the root user of the system -- or you have to enter
>#     the password on the serial console as the VGA console may not work!
>#   - a NFS share, for example "nfs://server:/export:/var/log/dump"
>#   - a CIFS (SMB) share, for example
>#     "cifs://user:password@host:/share/var/log/dump"
>#
># For the exact URLs, see kdump-url_parser(8) manual page. Or use the
># YaST2 kdump module to configure this if you're unsure.
>KDUMP_SAVEDIR="file:///var/log/dump"
>
>## Type:	integer
>## Default:	5
>#
># Specifies how many old dumps are kept.  If the number of dump files
># exceeds this number, older dumps are removed.
>#
># You can prevent the automatic removal by setting zero to this.
># Set KDUMP_KEEP_OLD_DUMPS to "-2" is you want to delete all old
># dumps before saving the new dump.
>#
># The default value is 5.
>#
>KDUMP_KEEP_OLD_DUMPS="5"
>
>## Type:	integer
>## Default:	64
>#
># Specifies the minimal free disk space (in MB unit) on the dump
># partition.  If the free disk space is less than the sum of this
># value and memory size, the default dumper won't save vmcore file
># in order to keep the system sane.

># Setting zero forces to dump without check.

>## Type:        string

># Specifies the dump device that is used for saving the dump with the kdump
># kernel. The dump device normally is a disk partition. You don't need to
># specify a dump device here. Then the dump is written to KDUMP_SAVEDIR when
># booting from the kdump kernel.
>#
># If KDUMP_DUMPDEV points to a device file, the dump is written to that device
># when running the kdump kernel. The advantage over writing the dump to
># disk immediately is that you don't have to mount the root file system (which
># may be corrupted!) just to write the dump. So if the root file system is
># corrupted, you have the chance to fix the file system manually and reboot the
># system without loosing the dump information. On the first normal boot which
># is able to successfully mount the root file system, the dump is saved to
># KDUMP_SAVEDIR as usual.
>#
># Important: The KDUMP_DUMPDEV is overwritten by kdump, so don't use it for
># saving any data. Also don't use the currently used swap partition.

>KDUMP_DUMPDEV=""
>
>## Type:        integer
>## Default:     3

># Determines if kdump uses verbose output. This value is a bitmask:
>#
># 1: kdump command line is written to system log when executing
>#    /etc/init.d/kdump
># 2: progress is written to stdout while dumping 
># 4: kdump command line is written so standard output when executing
>#    /etc/init.d/kdump
># 8: Debugging for kdump transfer script
>KDUMP_VERBOSE="3"
>
>## Type:        integer
>## Default:     0
>#
># Determines the dump level. If KDUMP_DUMPLEVEL != 0, then makedumpfile
># is used to strip pages that may not be necessary for analysing. 0 means
># no stripping, and 31 is the maximum dump level, i.e. 0 produces the
># largest dump files and 31 the smallest.
