Blade Why bind to LiveCD /proc before building initramfs ?
Imagine I have an unbootable system where I need to update the kernel image using
Code:
update-initramfs

.

I have seen numerous examples online which show the following

Code:
$ mount -t proc none /mnt/ubuntu/proc
$ mount -o bind /dev /mnt/ubuntu/dev
$ mount -o bind /sys /mnt/ubuntu/sys

After that we chroot into the broken OS and then execute the command to update the initramfs.

My questions are as follows-:
  1. Are we binding the /proc and /dev of the Live CD to the broken system ? Or are we binding the /proc and /dev of the broken system to the live cd ?
  2. If building the initramfs is dependent on the information of the OS for which the initramfs is built then won't it contain erroneous information if we build for the Live CD ? That is use the /proc and /dev of the LiveCD ?

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)
