NAME

mkdumprd - (Re)build the initramfs for kdump

SYNOPSIS

mkdumprd [options]

DESCRIPTION

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

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

•the kdump initrd should use no splash screen,

•the kdump initrd includes the kdump-save script and all required libraries.

This script calls dracut(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.

-k kernel, -K kernel

Specifies the kernel version or an absolute path to a kernel image (overrides KDUMP_KERNELVER from the kdump config file).

-I initrd

Specifies the resulting initrd.

-f

Force regeneration even if the configuration did not change.

-q

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

-d

Output debug information of the initrd build process.

-h

Shows help output and exits.

FILES

/etc/sysconfig/kdump

Kdump configuration. See kdump(5).
