Thank you for your bug report, I will fix this today or tomorrow.
I may also provide pre-compiled modules if there is request.

Great!
It would be nice to have a pre-compiled modules for i386, too.
Is that possible this pre-compiled aufs module could be included in the package linux-ubuntu-modules ?
Thank you very much.

I second that: it would be very nice to have aufs.ko included in linux-ubuntu-modules.

By the way, is lhash.patch included in the Ubuntu kernel for hardy? I'm trying to set up a diskless gutsy box using unionfs/aufs on the client. Unionfs just hangs and aufs complains about the lhash patch being missing :)

Regards,

Michael

Adding it to linux-ubuntu-modules would also allow us to use aufs for the livecd, like Debian does already.

Update: I've just taken a look at the Ubuntu kernel tree (using gitweb) and it seems that the lhash patch is not included.

Julian,
unless you can confirm that this patch is not needed anymore in current aufs I'll file against linux-source-2.6.24 soon. Sorry for hijacking your bug report, Steven :)

Great! I am not alone. Thanks, Michael.
Actually the reason I was trying to use aufs is because I had a problem with unionfs and squashfs both in Gutsy and Hardy-alpha3. I tried to use live helper from Gutsy to create an Ubuntu live. I did. However the problem is although the created ISO boots OK, I got kernel Oops about unionfs when udev detecting hardware. Attached is the dmesg output. I was wonder why gutsy/hardy-alpha3 desktop installation CD works fine, and mine did not.

I've just filed bug #182603 to get the lhash patch included in Hardy.

Steven,

Gutsy as well as Hardy still use unionfs 1.4.x which is rather old. I was actually expecting problems with unionfs because of past experiences - unionfs was very broken during the gutsy development cycle (which caused us Mythbuntu people lots of grief) until they reverted some changes, IIRC. It's odd that it's still not working as it's supposed to be fixed but I'm not very surprised :). Once that lhash patch is in Hardy, I'll test aufs again and if it's successful/more stable than unionfs, I'll keep bugging people until it's included in Hardy as a pre-compiled module :).

Michael,
Thanks for sharing your experience.
Yes, it would be nice to have aufs work with NFS, too.
As Julian mentioned, if aufs could be included in linux-ubuntu-modules, we can use aufs with live CD. It's even better.

Julian,
How about the status now ? This bug is fixed or not ? A pre-compiled module is available or not ?
Thanks in advance.

Just found newer kernel 2.6.24-5-generic (2.6.24-5.8) is in hardy, however, this bug still exists. Same error messages when compiling aufs on 2.6.24-5-generic.

I attached a debdiff which should fix all problems related to Kernel 2.6.24.
Needs to be uploaded.

No upload, I will upload a new upstream version to Debian, which can be synced.

Module aufs is included in linux-ubuntu-modules-2.6.24-7:
steven@hardy:~$ dpkg -L linux-ubuntu-modules-2.6.24-7-generic | grep aufs.ko

Cool!
Thanks!
