Comment 3 for bug 1457054

Fixed upstream:

However, there's one more detail to fix in unprivileged containers:

root@v:/# getpcaps $$
Capabilities for `608': = cap_chown,cap_dac_override,cap_dac_read_search,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_setpcap,cap_linux_immutable,cap_net_bind_service,cap_net_broadcast,cap_net_admin,cap_net_raw,cap_ipc_lock,cap_ipc_owner,cap_sys_rawio,cap_sys_chroot,cap_sys_ptrace,cap_sys_pacct,cap_sys_admin,cap_sys_boot,cap_sys_nice,cap_sys_resource,cap_sys_tty_config,cap_mknod,cap_lease,cap_audit_write,cap_audit_control,cap_setfcap,cap_syslog,cap_wake_alarm,cap_block_suspend,37+ep

The cap_audit_* are a lie, the audit subsystem in current kernels isn't namespace aware and thus unprivileged containers can't have these caps. The failed systemd-journald-audit.socket unit there isn't a big deal, but this should be fixed in LXC.
