3:59 p.m.
On the XO-1 under F11-XO1/os10, I patched with unionfs and recompiled the 2.6.31_xo
kernel, to include unionfs and some other modules.
Installed on the XO-1 with "make install".
Then I made the initrd with "dracut initrd_name kenel_version" (dracut-olpc
v0.30) and fixed the simlinks in /boot.
Everything looked good but rebooting resulted in a kernel panic with the attached message
(picture of the screen actually).
I do not really know if the problem is with the kernel or the initrd or both (the message
title can be misleading-just a guess) but the initrd is really huge, ~18MB compressed (!)
and the mount complains might be indicative.
Should I have added specific dracut command line options or change the (any) config file?
Sorry for asking here but I couldn't find any xo-dracut howto.
Thanks for any suggestions/pointers.

Um. Not pretty. AIUI, reinstalling the kernel rpm re-runs the correct
dracut+kernelmods magic, you could try that. However, this may be
broken now that we are using versioned FSs again.

If I only knew what you mean and how to do that?... :-)
If the idea is to "recover" my XO this is done already.
If you mean that reinstalling (some) kernel rpm will correct the dracut process and allow
me to build the new initrd, I have no clue.
Just to point out that I did not use rpmbuild for the new kernel. Just "make
oldmenuconfig/make/make modules_install/make install"
However, this
may be
broken now that we are using versioned FSs again.

The XO-1 releases are not currently using a versioned FS. That is something I
hope to work on this weekend at FUDCon.

The way we develop is that we make changes to the kernel, commit it to
git, then:
make clean distclean
make xo_1-kernel-rpm
(or xo_1_5-kernel-rpm)
Then you have a kernel RPM that you can install on the XO, which will
take care of the initramfs for you.
If you choose to develop another way then you're going to have to look
carefully at the rpm spec file and make sure that you reproduce all the
little things that it does.

OK. I'll try learn more about git till then could you if this work flow has major
flaws _if done locally_ ?
git clone git://dev.laptop.org/olpc-2.6
cd olpc-2.6
commit -a # is the tree included already?
(patch kernel) # do I need to "git add" the patch file and the file/folders that
the patch generates?
make clean distclean # this goes here, right?
make xo_1_defconfig
make menuconfig
make
commit -a #do I need this for the next steps?
make xo_1-kernel-rpm
Yes?
Thx for your help (I know is a very busy time)

Yes, add all your changes and make a commit at this point.

Yes
make xo_1_defconfig

Drop all these

Then do this.

Excellent, thanks.
This makes building a breeze but patching/configuring a nightmare (for me). Is there any
special kernel patching/configuration tool or everything is done manually?
Oh well, maybe when XO-1.5 os is out.

A nightmare, how?
All it is is downloading the kernel source, patching it and compiling
it. I don't see how it could be done any other way.

OK. I'm lost
Cloning the Git olpc-2.6 a) kernel patches fail b) a lot of kernel sources are missing.
Thus a nightmare.
From what I understood "make xo_1-kernel-rpm" will work only
with the git clone and _not_ with the kernel src.rpm. Is that wrong. Does it also work
with the kernel sources provided in http://xs-dev.laptop.org/~dsd/repos/f11-xo1/ ???
(I guess I could try it :-)

are you doing git-checkout to get the right branch? Right after the

No I didn't. I guess the "olpc-2.6.31" is the branch of interest at the
time. Correct??
Does your replay also means that "make xo_1-kernel-rpm" will _not_ work with
kernel src.rpm and/or that "normal" 2.6.31 kernel patches should work on the
olpc-2.6.31 git branch?
Thx

Bingo! I think olpc-2.6.30 is your friend -- but check whatever the
latest builds have.
