Hi, I'm trying to update my kernel and currently failing to build
2.6.36.3 with a git checkout from an hour ago (18th Jan 2011) of
git-standalone
I'm building into the kernel (not a module). I don't immediately
suspect kernel .config, but abbreviated version below. Errors on
compile are:

Hello
this is, instead, the behaviour with 2.6.35 kernel:
aspi2 ~ # uname -r;mount -o remount,noxino,ro /etc
2.6.35-gentoo-r12-live
/sbin/mount.aufs:plink.c:220: proc: No such file or directory
aspi2 ~ # grep aufs /proc/mounts
rootfs / aufs rw,relatime,si=9a4f331f 0 0
etc /etc aufs
Marco Clocchiatti:
remount /etc, as in your tip, I have the same behaviour.
etc becames anavailable (Resource temporarily unavailable) and the
system needs hardware reset.
Then please show me the output of strace -f fo remount /etc.
aspi2 ~ # uname -rm;strace -f mount -no remount,noxino,ro /etc
2.6.36-gentoo-r5-live i686
execve(/bin/mount, [mount, -no, remount,noxino,ro, /etc],
[/* 50 vars */]) = 0
brk(0) = 0x8494000

Thanx.
But it doesn't look end.
Do you mean that remount hung?
yes, it do.
I read a lot of -1 EINVAL (Invalid argument) for directories which
should be accessible in a normal configuration.

Let me make sure.
- remount didn't end.
- you could see many EINVAL in your strace -f mount -no

thanks again.
-i option seems really usefull, for me :)
may it be this better for you?

Let me make sure again.
- with -i, remount process exits.
- and all other operations, ls(1) or something, worked correctly.
If so, I'd want you to test these commands just before remount
using sys-fs/aufs2-0_p20101122-r1 from a gentoo distribution and
gentoo-sources-0_p20101122-r1, system hungs at shutdown when etc is
remounted read-only.
I mount etc with aufs in early-userspace.
the problem may it be reproduced with a simple:
mount -o remount,ro /etc
after the command, /etc is

I have been working on the aufs2.1 modification for 2.6.36,

Hello Joseluis an list,
you should post in english, because this is the language of that list,
aufs for linux kernel 2.6.36 is under development, so we must think
seriously about including it in a user's kernel.
The patch is easy to install in the kernel sources, and then we

So you tell me I've to use aufs2-standalone-patch also.
That is new for me. Will try your new set then using your order.

There seems to be other patches in my git repository which are necessary
before the patch I sent.
Until I have enough time, I won't be able to merge them.
As you might know, it is equivalent to create a full patch to support
2.6.36.

I'm glad for any help on this problem. Steven Barrett might have also time to

Hi Junjiro,
Does AUFS2.1 support 2.6.36? I tried a couple weeks ago and it would not
compile.
Thanks for your excellent software,

Hope this doesn't double post, it bounced back the first time

Unfortunately I don't have enough time to keep sitting in front of my PC

While I am not sure when it will be, I am trying
