[Bug 405195] [NEW] When stopping a specific daemon, _all_ routes are flushed

[Tore Anderson]

Public bug reported:

Binary package hint: quagga

This misbehaviour just bit me:

root at fwtest1:~# /etc/init.d/quagga stop ospf6d
Stopping Quagga daemons (prio:0): ospf6d.
Removing all routes made by zebra.

So I'm stopping ospf6d only, but _all_ routes, including the ones
installed by still-running processes such as bgpd, ripd, and so on, are
removed from the kernel's routing table.  That can't be right.

I suggest applying the following patch so that the flushing will only
happen if all of the Quagga daemons are stopped:

--- /etc/init.d/quagga	2009-05-06 23:47:31.000000000 +0200
+++ /tmp/quagga.new	2009-07-27 10:30:44.000000000 +0200
