** Description changed: + ==================================== + SRU Justification + Impact: xenial containers cannot be rebooted + Fix: shorten the fuse directory entry caching time, and make lxc (when using lxcfs) wait at least that amount of time during reboot. + Test case: + lxc-create -t download -n x1 -- -d ubuntu -r xenial -a amd64 + lxc-start -n x1 + lxc-attach -n x1 -- rebot + sleep 10s + lxc-attach -n x1 -- ifconfig -a + (Note this requires lxc 1.1.5 which is currently in wily-proposed + in order to work at all) + ==================================== + Even after fixing bug 1497420 rebooting containers with systemd >= 226 (i. e. with supporting unified cgroups) does not work. Build a standard xenial container (using the ubuntu template; e. g. "adt-build-lxc ubuntu xenial"), start it: - sudo lxc-start -n adt-xenial -F + sudo lxc-start -n adt-xenial -F then log in and run "sudo reboot". It shuts down, but reboot fails with Rebooting. systemd 227 running in system mode.
