Would it help you if you could start up the peer config and all attached
child configs would be started automatically, i.e. in our example
scenario

  ipsec up net-net

would start net-1, net-2, and net-3. This would happen only in the case
when there is no child config having the same name as the peer config.

In the past usually two IKE_SAs and corresponding CHILD_SAs were
established and maintained over all subsequent rekeyings. This is
not harmful per se but creates twice the number of tunnels. I have
to check if the the INITIAL_CONTACT notification introduced with
strongSwan 4.5.1 has changed this behaviour.

I even didn't know that this statement was present in the ipsec script.
Probably has been there since the early FreeS/WAN times. So just forget
about it.

Hmmm, rotation of log files doesn't seem to be supported. Only if you
use the syslogger.
