Ubuntu 11.10 shipped with both aufs and overlayfs. Arkose on 11.10 only support aufs.
Starting with arkose in 12.04, both aufs and overlayfs are supported (though it'll print an error if overlayfs isn't around but continue anyway). You could try with the newer arkose on 11.10 by taking it from ppa :arkose-devel/stable It sounds like the problem here is that the "virtual" kernel in the cloud images has been so stripped down that we simply don't have the needed modules for arkose to work. I believe 12.04 switched to a more complete kernel for cloud images so hopefully that got fixed. Alternatively you could try to use the "bind" instead of the "cow" option which is a lot more limited but won't use aufs. I'm marking this bug as won't fix at least as arkose is concerned as there's little I can do if the kernel doesn't contain the required modules. ** Changed in: arkose (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947226 Title: arkose fails on AWS EC2 with 11.10 instance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/arkose/+bug/947226/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
