+.SH NAME
+mkdumprd \- creates initial ramdisk images for kdump crash recovery
+.SH SYNOPSIS
+\fBmkdumprd\fR [OPTION]
+
+.SH DESCRIPTION
+\fBmkdumprd\fR creates an initial ram file system for use in conjunction with
+the booting of a kernel within the kdump framework for crash recovery.
+\fBmkdumprds\fR purpose is to create an initial ram filesystem capable of copying
+the crashed systems vmcore image to a location specified in \fI/etc/kdump.conf
+
+\fBmkdumprd\fR interrogates the running system to understand what modules need to
+be loaded in the initramfs (based on configuration retrieved from
+\fI/etc/kdump.conf)\fR
+
+\fBmkdumprd\fR add a new \fBdracut\fR module 99kdumpbase and use \fBdracut\fR
+utility to generate the initramfs.
+
+\fBmkdumprd\fR was not intended for casual use outside of the service
+initialization script for the kdump utility, and should not be run manually. If
+you require a custom kdump initramfs image, it is suggested that you use the
+kdump service infrastructure to create one, and then manually unpack, modify and
+repack the image.
+
+
+.SH OPTIONS
+.TP
+All options here are passed to dracut directly, please refer \fBdracut\fR docs
+for the info.
