# TODO list!
#
# - we need to find a way allow the user to choose whether to start the
#   event manager at _all_ the logins, and if that's the case, lock all
#   kind of sessions (terminal _and_ X);
# - upstream should probably migrate the configuration of the event
#   manager on a per-user basis, since it makes little sense to be _all_
#   system-level configuration;
# - we should probably provide some better config support that ensures
#   the configuration to be valid, as well as creating the symlinks;
# - we should probably add support for nss;
# - we should move the configuration in /etc/security as for the rest
#   of PAM-related configuration.
