aufs support/patch for kernel 2.6.34.1

author_unknown · 08-18-2010, 01:23 AM

Hi,
I need aufs support/patch for kernel 2.6.34.1 as i i need to create a live linux distro for my organization and linux live scripts (the scripts which I am using for creating live linux distro) require aufs and squashfs support. There is a directive for squashfs in kernel configuration file but nothing for aufs and the patch available at linux-live site seems not to work. Any guidance/pointers would really be appreciated.

PS: For security reasons the kernel needs to be monolithic i.e. without loadable modules support.

Thanks,
AU

I have the 2.6.34 zen kernel source pre-patched, etc
and the reason the original lls 6.3.0 wont work is cause it has squashfs 3.4; Ritchie at Slax forum has made a newer version of Linux-Live-Scripts that works with the 2.6.34 kernel

I have a kernel kit available that will enable you to create a livecd using arch/slackware, not tested on any others...

Hi Linus72,
thanks for the reply. I cannot get ahead with the .txz file as I am unable to figure out how to make it work on centos. If possible for you can u send me ur patched kernel(source would be appreciated), initrd, config file and System.map file

Hi AlucardZero,
Can u tell me how can i apply this patch to my kernek. it is in lzma format. I downloaded "lzma" and decompressed it using lzma -k but when i am trying to patch the kernel it asks me the name of file to patch. Can you please help me out.

linus72 · 08-20-2010, 06:46 AM

ok
to decompress a .txz just do

Code:

tar xJvf /path/to/.txz

as for the source, which is prepatched
I also yesterday added the bfq patches for it too
heres those patches
http://algo.ing.unimo.it/people/paol...s/2.6.34-zen1/

to patch the source I put the patches in /usr/src along with the kernel source and did

Code:

patch -p1 < ../0001-block-prepare-I-O-context-code-for-BFQ.patch
patch -p1 < ../0002-block-add-cgroups-kconfig-and-build-bits-for-BFQ.patch
patch -p1 < ../0003-block-introduce-the-BFQ-I-O-scheduler.patch

then did "make menuconfig"; edited for bfq under
"Enable The Block Layer"/"IO Schedulers"
its set for cfq right now..

anyway; heres the BFQ patched source, it's .tar.bz2

or just extract the .txz you have and patch yourself

Hi,

I downloaded ritchie's crripts from http://rapidshare.com/files/39626845....0_x86.tar.bz2

and everything went well with clean exit status(every command on echo $? showed exit status to be 0)

but when i tried to boot from the cd created i got the following error
"fatal error occured: mylinux data not found"

you can find the snapshot of the error in the attached file.

Any ideas how to get rid of it.

well, I'm not sure
you should use the linux-live from me which I have modified even more than Ritchie's
its in the arch/slackware kernel kits here
http://multidistro.com/NFLUXNEW/SQ4/kkits/kkits.html

just download the arch x86 one and extract it and the linux-live is in there...

you compiled kernel too right?
did you change something?

author_unknown · 08-23-2010, 06:40 AM

yeah the kernel did compile fine.... and i have also added the loadable module support and applied the aufs patch... the system which i want to turn live is booting fine on the machine but displays the above error when made to turn live using lls scripts

BTW i forgot to mention I am using centos so I dont think your things would work for me... if possible please provide me your LLS scripts which u used to turn ur system live

linus72 · 08-23-2010, 06:49 AM

the linux-live in the arch/slackware kernel kits will work for any system probably

there was already a aufs patch applied....why repatch it?

author_unknown · 08-23-2010, 08:10 AM

ok
to decompress a .txz just do

Code:
tar xJvf /path/to/.txz

I did it but a got an error stating invalid option --J

do i need to install any application for extracting .txz file???

so are you trying to make a Centos5 livecd?
or what?

and you said kernel needs to be monolithic?
so that means your gonna compile all modules into kernel vs being loadable modules?
