Subject: [PATCH] use >> (append) instead of > for sysctl.conf updates

I'm afraid current script would clobber existing /etc/sysctl.conf configuration
AND each of the 3 changes clobbering would clobber the previous one(s), only the last "net.ipv6.conf.lo.disable_ipv6=1" would be persisted in sysctl.
