Recently in the update, one problem in /etc/sysconfig/network-scripts/ifdown-ipv6 emerged.
The script tries to *always* shut down the 6to4 interface, this results to following behaviour
if only NETWORKING_IPV6=yes is defined in /etc/sysconfig/network (that is, a very simple case):
# ifdown eth0
ERROR : [ipv6_trigger_radvd] Given pidfile '/var/run/radvd/radvd.pid' doesn't exist,
cannot send trigger to radvd
This can be remedied by the attached, quite trivial patch.
This doesn't look nice, so should be fixed ASAP.
Created attachment 53685 [details]
patch to fix the problem of always shutting down 6to4 at ifdown-ipv6.
