Long story short, I had a ps3 with both Lenny and Sid repositories. Knowing this is a bad idea and that Lenny is being deprecated I decided I wanted to move everything to Sid. I changed my repos and ran apt-get-update, upgrade, dist-upgrade. Had one warning during the apt-get upgrade that version of HAL I was about to install would not be supported by the kernel. I figured dist-upgrade would add a new kernel and if not I had made a backup. I proceeded and after rebooting I just have an "initramfs" prompt instead of a kde login screen. There's no apt or dpkg and it seems my backup file may be corrupted as it does not open now...
I would like to get this up and running again, preferably with Sid.
If anyone has ANY advice it would be MUCH appreciated.
Imagine I have an unbootable system where I need to update the kernel image using update-initramfs.
I have seen numerous examples online which show the following
$ mount -t proc none /mnt/ubuntu/proc
$ mount -o bind /dev /mnt/ubuntu/dev
$ mount -o bind /sys /mnt/ubuntu/sys
After that we... (8 Replies)
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)
What's the correct way to change the initramfs file that's used during boot?
I know that it's a gzipped cpio archive, but when I gunzip, extract, re-archive (without changing any files), and gzip, then the result is that the system does not boot any more. And I even set the cpio archive type.

MKINITRAMFS(8) mkinitramfs manual MKINITRAMFS(8)NAME
mkinitramfs - low-level tool for generating an initramfs image
SYNOPSIS
mkinitramfs [-c compress] [-d confdir] [-k] -o outfile [-r root] [-v] [version]
mkinitramfs [--supported-host-version= hversion]
mkinitramfs [--supported-target-version= tversion]
DESCRIPTION
The mkinitramfs script generates an initramfs image. The initramfs is a compressed cpio archive. The archive can be used on a different
box of the same arch with the corresponding Linux kernel. mkinitramfs is meant for advanced usage. On your local box update-initramfs
calls mkinitramfs with the relevant parameters. update-initramfs keeps sha1sum of generated initramfs. It takes care to generate backups
and eventually runs the bootloader.
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 -c compress
Override the COMPRESS setting in initramfs.conf.
-d confdir
Set an alternate configuration directory.
-k Keep the temporary directory used to make the image.
-o outfile
Write the image to outfile.
-r root
Override the ROOT setting in initramfs.conf.
-v Set the verbose mode output.
version
Set the kernel version of the initramfs image (defaults to the running kernel).
--supported-host-version=hversion
This option queries if mkinitramfs can create ramdisks on a running kernel of version hversion.
--supported-target-version=tversion
This option queries if mkinitramfs can create ramdisks for kernel version tversion.
ENVIRONMENT
mkinitramfs honours the TMPDIR environment variable. If set, it uses subdirectories in the given directory to create its temporary working
directories. Else it uses /tmp as default value for that purpose. The given directory should be on a filesystem which allows the execution
of files stored there, i.e. should not be mounted with the noexec mount option.
FILES
/etc/initramfs-tools/initramfs.conf
The default configuration file for the script. See initramfs.conf(5) for a description of the available configuration parameter.
/etc/initramfs-tools/modules
Specified modules will be put in the generated image and loaded when the system boots. The format - one per line - is identical to
that of /etc/modules, which is described in modules(5).
/etc/initramfs-tools/conf.d
The conf.d directory allows one to hardcode bootargs at initramfs build time via config snippets. This allows one to set ROOT or
RESUME. This is especially useful for bootloaders, which do not pass an root bootarg.
/etc/initramfs-tools/DSDT.aml
If this file exists, it will be appended to the initramfs in a way that causes it to be loaded by ACPI.
EXAMPLES
Create an initramfs for current running kernel:
mkinitramfs -o ~/tmp/initramfs-$(uname -r)
Create an initramfs for specific kernel and keep builddirs:
mkinitramfs -k -o ~/tmp/initramfs-2.6.21-686 2.6.21-686
Debug initramfs creation (check out written logfile)
sh -x mkinitramfs -o ~/tmp/initramfs-$(uname -r) 2> ~/tmp/log
