NAME

       mkdumprd - (Re)build the initramfs for kdump

SYNOPSIS

       mkdumprd [-h] [-q] [-f] [-k kernelver] [-i opts]

DESCRIPTION

       mkdumprd (re-)builds the kdump initrd. For kdump, a special initrd is used because

       o   the kdump initrd should include network modules and network configuration (and therefore is larger as the normal initrd used for
	   booting),

       o   the kdump initrd should use no splash screen,

       o   the kdump initrd includes kdumptool(8) and all required libraries.

       This script calls mkinitrd(8) with all required parameters. If the initrd already exists, it checks first if the configuration file or the
       kernel are newer, and only rebuilds the initrd if necessary.

OPTIONS

       All option parsing is done via the getopt(3) function, and therefore follows all standard command line parsing rules.

       -h | --help
	   Shows help output and exits.

       -k kernelversion
	   Specifies the kernel version. If no version is specified and also no kernel or initrd are specified, then mkdumprd uses kdumptool(8) to
	   find out the correct kernel and initrd.

       -K kernel
	   Specifies the kernel binary. If you specify that option, also specify -I.

       -I initrd
	   Specifies the resulting initrd. If you specify that option, also specify -K.

       -q
	   Be quiet. Don't output status messages. Used to call mkdumprd(8) from /etc/init.d/kdump init script.

       -i parameters
	   Append the specified parameters to mkinitrd(8) call.

FILES

       /etc/sysconfig/kdump
	   Kdump configuration. See kdump(5).
