AFAIK/recall none of the ipv6 disabling in the /etc/sysconfig files has
ever quite worked the way it was advertised, I ended up writing a small
shell script to be executed on startup to handle the issue. something like:
echo "disable ipv6 on physical interfaces"
for i in /proc/sys/net/ipv6/conf/eth*
do echo 1 > $i/disable_ipv6
done
but you may have better luck.
