Please test with aufs2-0_p20090601-r1 (in tree after your next regular sync) and report back.
Hmmm how do I emerge an ebuild that is masked because of missing keyword? Konstantin
Sorry, missed the keyword for x86, just added it, so should be there for your next scheduled sync.
Hi, still does not work: * Updating module dependencies for 2.6.29-gentoo-r5 ...

Did you compile your patched kernel and booted it before loading the aufs2 module?
What do You mean 'patched kernel' did the aufs ebuild patch something in /usr/src/linux that requires a reboot? If yes I did not, and this might explain it :) regards, Konstantin

So if you did use an ebuild prior to 0_p20090601-r1, then it will be patched. With the current version, it will ask you to either patch it manually or enable the "kernel-patch" useflag, if the kernel is not already patched. So yes, you have to run all steps needed to compile, install and boot the current kernel again, then it should work. Please report back after that.
OK this works. Just that I have the problem that it seems aufs doesn't work with xfs which is used on the box I am testing with, but this is another problem. Thanks Konstantin

The author is responsive and very helpfull whereever it is possible for him. ;-) Closing this bug as invalid since the reason was not in the source nor in the ebuild.
