I tested it on a kernel with the FS_USERNS_MOUNT and USER_NS enabled, the problem persists. So it doesn't look like a bug of aufs, but still thanks for your help! Florian Am 30.09.2013 11:46, schrieb Florian Klink:
[[1]1]sf...@users.sourceforge.net: Florian Klink: I use Arch Linux (amd64) using the "zen-kernel" (tree on zen-kernel.org, linus' kernel plus some nice additional features like UKSM and aufs3). The package is called "linux-zen" in Arch Linux. Now I am installing Arch Linux... Just to test the kernel? You can get the location of the git tree and the default config from here: [2][2]https://aur.archlinux.org/packages/linux-zen/?setlang=en I hope the problem will automatically go away, when aufs supports user namespaces (as the remount will then happen only inside the namespace of the machine). I therefore mailed you a "git-compatible" patch of Bhushan Jain's changes a minute ago. Does it mean that FS_USERNS_MOUNT solved the problem? Are you sure? I tested the same on a kernel without enabled user namespaces and a loopback ext4 fs mounted on the location of the container root (no aufs involved), it also got remounted read-only. So it doesn't seem to be really a "bug of aufs". But I'm not yet sure how enabled FS_USERNS_MOUNT of the "root filesystem" will affect a remount of it inside an lxc container... I will build a kernel with enabled user namespaces, aufs FS_USERNS_MOUNT patch applied and will let you know how this one works. Florian J. R. Okajima References 1.
