The recovery function should/probably/hopefully only check for the really required drivers for your platform.
So let me get this straight. What you are saying is that 90% percent of the using the /proc and /dev of the LiveCd will not cause any problems because they are very similar to the original system that I will boot into.

Am I correct in my assumption ?

change initramfs by hand?

What's the correct way to change the initramfs file that's used during boot?

And I even set the cpio archive type. ... (18 Replies)

initramfs on 2.4 kernel

Is there a patch available to support initramfs on the 2.4 kernel? We can't upgrade to 2.6 for legacy purposes. All I found on google were early references to how initramfs is better than the 2.4 initrd. Thanks much! (0 Replies)

update-initramfs

UPDATE-INITRAMFS(8)					      update-initramfs manual					       UPDATE-INITRAMFS(8)

NAME

       update-initramfs - generate an initramfs image

SYNOPSIS

       update-initramfs -c|-d|-u [-k version] [-t] [-v] [-b] [-h]

DESCRIPTION

       The  update-initramfs  script manages your initramfs images on your local box.  It keeps track of the existing initramfs archives in /boot.
       There are three modes of operation create, update or delete.  You must at least specify one of those modes.

       The initramfs is a gzipped cpio archive.  At boot time, the kernel unpacks that archive into RAM disk, mounts and uses it as  initial  root
       file system. All finding of the root device happens in this early userspace.

OPTIONS

	-k  version
	      Set  the	specific  kernel  version for whom the initramfs will be generated.  For example the output of uname -r for your currently
	      running kernel.  This argument is optional for update. The default is the latest kernel version.

	      The use of "all" for the version string specifies update-initramfs to execute the chosen action for all kernel  versions,  that  are
	      already known to update-initramfs.

	-c    This mode creates a new initramfs.

	-u    This mode updates an existing initramfs.

	-d    This mode removes an existing initramfs.

	-t    Allows one to take over an custom initramfs with a newer one.

	-v    This option increases the amount of information you are given during the chosen action.

	-b    Set an different bootdir for the image creation.

	-h    Print a short help page describing the available options in update-initramfs.

EXAMPLES

       Update the initramfs of the newest kernel:

       update-initramfs -u

       Create the initramfs for a specific kernel:

       update-initramfs -c -k 2.6.18-1-686
