Description of problem: If the /etc/machine-id file doesn't exist, systemd installs a temporary machine-id file which is bind-mounted to /run/systemd/machine-id. Because of this, it has the wrong context (system_u:object_r:init_var_run_t:s0 instead of system_u:object_r:etc_runtime_t:s0), which prevents systemd-journald from starting. Version-Release number of selected component (if applicable): 3.10.0-125.fc17 How reproducible: Always, when systemd is enforcing Steps to Reproduce: 1. Remove /etc/machine-id 2. Reboot Actual results: Machine starts up normally. Expected results: systemd enters emergency mode because of systemd-journal failure.
