Lxc mounts the mount point by directly using the syscalls without invoking the mount(3) command. The mount command rely on /etc/mtab to write and read information. Depending on what does your distro, that is invoking mount or not, /etc/mtab may be different. If you want to check the consistency, you should look at /proc/mounts of each container. > I only noticed it when after I restarted the container with the above > mount output, devpts was re monted read only on the host. Make sure the distro you are running is mounting devpts with the new_instance option. > This is the config: > > root@box ~ # cat /etc/lxc/node1.spiked.uk.com > lxc.utsname = node1.spiked.uk.com > > lxc.pts = 1024 > > lxc.mount = /etc/lxc/node1.spiked.uk.com_fstab > lxc.rootfs = /home/stuff/lxc/node1.spiked.uk.com > > lxc.network.type = veth > lxc.network.flags = up > lxc.network.link = br0 > lxc.network.hwaddr = 52:54:00:00:16:79 > lxc.network.ipv4 = 10.63.74.97 > lxc.network.name = eth0 > root@box ~ # cat /etc/lxc/node1.spiked.uk.com_fstab > none /home/stuff/lxc/node1.spiked.uk.com/dev/pts devpts defaults 0 0 > none /home/stuff/lxc/node1.spiked.uk.com/proc proc defaults 0 0 > none /home/stuff/lxc/node1.spiked.uk.com/sys sysfs defaults 0 0 > none /home/stuff/lxc/node1.spiked.uk.com/dev/shm tmpfs defaults 0 0 > > Regards ------------------------------------------------------------------------------ Xperia(TM) PLAY It's a major breakthrough.
