Just for posterity: you needn't restrict yourself to signals.  Logrotate
has nothing to do with signals.  Signals are a rather limited form of
IPC, which might be a good tool for some applications.  Both Pacemaker
and Corosync already employ much richer IPC mechanisms, which might be
more natural to extend for triggering log rotation than adding a new IPC
mechanism.  Logrotate optionally runs scripts before and after renaming
the log files; these can invoke kill, corosync-cmapctl, cibadmin and so
on all the same.  It's entirely your call.
