Description Mumia W. 2008-07-25 09:06:22 UTC
Latest working kernel version: (none)
Earliest failing kernel version: 2.6.26
Distribution: Ubuntu 8.04
Hardware Environment: i386
Software Environment: linux-source, kernel_package
Problem Description:

I would like to see UUID support built into the kernel; in particular, I would like to be able to do this in Grub:

> title  Ubuntu 8.04.1, kernel 2.6.26
> root   (hd0,7)
> kernel /boot/vmlinuz-2.6.26 rootuuid=aaaabbbb-cccc-dddd-eeeeffff ro
> boot

In other words, the "rootuuid" parameter would specify the UUID of the hard disk to use as the root partition, and no initrd or initramfs would be needed.

This request has come out of a thread I created in the Ubuntu-users mailing list:
http://home.earthlink.net/~mumia.w.18.spam/docs/nouuid-1.txt
http://home.earthlink.net/~mumia.w.18.spam/docs/nouuid-2.txt

Steps to reproduce:

Specify rootuuid=aaaabbbb-cccc-dddd-eeeeffff, and it will be ignored if there is no initrd or initramfs.

Specify root=UUID=aaaabbbb-cccc-dddd-eeeeffff, and it will be ignored if there is no initrd or initramfs.

Sorry, we can't take feature requests in bugzilla. If you want to have better luck with this, you should start the effort off yourself and post it on the appropriate mailing list.

> and it will be ignored if there is no initrd or initramfs.
--> but if someone wants to harm the system (as suggested) he would place a initrd or initramfs

sorry links are dead:
