Top Forums UNIX for Advanced & Expert Users How to view Ramdisk Initialization Process Post 302537956 by pludi on Monday 11th of July 2011 07:30:08 AM

You can view messages from the kernel using dmesg. These may or may not contain information about initrd. But basically there's not much happening: the kernel reads the file provided at the command line, unpacks it, and runs the init binary contained within.

The only way I can think of to get more information would be to attach to a kernel debugger interface, if present.

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). BUGS
