How to recover your system:
---------------------------

You need to manually set up what is needed in your case
to boot the kernel (by default named kernel-HOSTNAME)
plus initramfs/initrd (by default named initramfs-HOSTNAME.img)
that contains the Relax-and-Recover rescue/recovery system
on your replacement hardware.

For example to directly boot the ReaR recovery system from within
a Linux system that is already running on your replacement hardware
you may use 'kexec':

1. Copy the kernel and the ReaR recovery system initramfs
   on your already running Linux system.

2. Load the kernel and ReaR's initramfs and provide an appropriate
   kernel command line to run the ReaR recovery system in a ramdisk
   and use standard VGA 80x25 text mode (one single command line):

kexec -l kernel-HOSTNAME
           --initrd=initramfs-HOSTNAME.img
           --command-line='root=/dev/ram0 vga=normal'

You may have to add hardware dependant kernel command line
   parameters if needed for your replacement hardware,
   cf. /proc/cmdline of your system.

3. Boot the loaded kernel (plus ReaR's initrd):

kexec -e

That will instantly reboot into the loaded kernel without
   a clean shutdown of the currently running Linux system.

4. In the booted ReaR recovery system log in as 'root'
   (this may only work directly on the system console) 
   and recover your system:

rear recover

That will completely replace the Linux system from before
   so it does not matter when it was not cleanly shut down.
