I think vorlon's patch to improve the shm upgrade broke some particular cases. I've got a patch to fix it in progress. However, I do need to work out how to deal with all possible combinations of: /dev being a mountpoint /dev/shm being a mountpoint /run being a mountpoint /dev/shm being a symlink or directory /run/shm being a symlink or directory We need to take special care never to alter the bind mounted host environment, so as to not alter any state where a mountpoint is present. I should hopefully have time for this tonight. It's not such a combinatorial explosion as indicated above--if any mountpoints are present it restricts what we can do. So e.g. if /dev is a mountpoint and /dev/shm is a symlink, then /run/shm must be a directory since we can't alter the symlink. And vice versa if it's a directory, then /run/shm must be a symlink.
