Hi,
I have some problem while booting inside linux,so
tried to boot in single user mode for some changes in
/etc/grub.conf.But iam not able to boot in single user
mode.It is giving error message as
ds: no socket drivers loaded!
VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00
Please i need a solution to proceed my work as soon
as possible.

Hi,
1.) no need to post the same message twice. This is a mailing list so it
may take some time until a response is written.
2.) This is the absolute wrongest list you could find for your question.
This mailing list is for linux kernel development. Here we discuss bugs
and pachtes for the linux kernel. We DO NOT answer "I fubared my
computer, plz help"-type of questions.
There are enough linux communities who can help you with your problem
(e.g. linuxquestions.org) please refer to them.

change root=LABEL=/ to root=/dev/XXX. Vanilla doesn't support this...
Next time, use google first. And when you decide to writo to lkml, choose better
Subject.

is there a kernel patch that does allow it?

Yes, in RedHat's/Fedora's kernels since ages.

Label processing in Red Hat/Fedora distributions is not handled in the
kernel at all (thus you won't find a patch). It's all done in user space
via the initrd and works with vanilla kernels without a problem.

ehhh??
sure it does.
this is not a kernel feature, but an initrd feature, independent on
which kernel is used (there never was and is not a patch for this in any
distro kernel I know about)

wrong.
there is NO kernel patch for this. Not in RHs and not in Fedora's
kernel.
Never was either.
it's 100% done in the initrd.

Isn't this a matter of the bootloader ?

Oooops, sorry.

No, because it is merely used as a kernel parameter (which led me to the
false conclusion that it is done within the kernel) and the kernel
either mounts the root filesystem (without initrd) or it is handled
within the initrd (if you have one).

The boot loader knows very little and the BIOS may not even be able to
drive some of the hardware to go looking for volume labels. The sequence
used is that the initrd is the root file system and contains application
code run very early on in order to find out where the 'real' root fs is
by label. Having mounted that it can then pivot_root() itself into the
final desired configuration.
All userspace, and all the initrd building is done by a tool called
mkinitrd.

... which gets done for you automatically if you use "make install" from
the kernel sources after building. In addition "make install" is nice
enough for you to add the new kernel to your bootloader.
(and no this isn't a kernel patch either; "make install" basically has a
hook for a distribution specific script to be run, which at least for
Fedora causes the initrd to be made and the kernel+initrd to be added to
the bootloader)

So does someone have a kernel-side patch for enabling LABEL=? (Is the
kernel even able to tell the label of a filesystem, or is that specific to
mount(8)?)

I'm not aware of one existing.

currently the kernel is fully unaware of any labels, other than having
the space reserved in the various filesystem on disk metadata.
This is one of those things that is better done in userspace really.....
Hello,
do you have RAID array or a newly confiured RAID

What do you want to know ? Ask questions specifically mentioning the
problem in detail !
Also Please start new threads/topic for questions not related to any
other previous topic !

Sorry Sameer, I think you want to ask this from Jan Engelhardt which I
misunderstood that you are asking some new question as your reply
getting off-the-topic !
