uptime reads /proc/uptime which is gets you the time since the kernel was started. There are a few ways of "fixing" that issue: - Implement a new time namespace allowing us to reset the time to 0 when spawning a new container. - Use the fuse filesystem that was described at plumbers (some kind of lxcfs) that will let us generate the right value in userspace and bind-mount it over /proc/uptime in the container. The first is I believe the right way to do it, though it's not an high priority namespace, we have the user namespace, device namespace and syslog namespace that seem to be more pressing. The second solution is a good temporary workaround that'd equally apply to /proc/cpuinfo, /proc/meminfo, ... and wouldn't require any change in the kernel (or even lxc for that matter). -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
