Hi, I'm running lxc-1.0.6-r1 on Gentoo. I can create my lxc container and ssh into it and everything looks fine.
lxc-create -n u1 -t download -- --no-validate --dist ubuntu --release trusty --arch amd64 lxc-start -n u1 However, lxc-attach runs programs in the host's root, not in the container root: lxc-attach -n u1 ls /tmp This lists files in the *hosts* /tmp. The guest's /tmp is empty Looking at /proc/$PID/mountinfo in host and guest, I see that processes created inside the guest are chrooted to the right place: (in lxc guest, init is chrooted) head -1 /proc/1/mountinfo 81 124 0:2 /etc/lxc/u1/rootfs / rw - rootfs rootfs rw,size=16332604k,nr_inodes=4083151 However, programs run by lxc-attach are not chrooted lxc-attach -n u1 -- head -1 /proc/self/mountinfo 82 82 0:2 / / rw - rootfs rootfs rw,size=16332604k,nr_inodes=4083151 What config options could break this? I created a small program that just does nsexec [1], and it has the same behaviour. somehow, setns() is not setting the root fs properly using processes running in lxc.
