The rc.d/auto_linklocal script does this:
auto_linklocal_start()
{
if ! checkyesno ipv6_enable; then
${SYSCTL_W} net.inet6.ip6.auto_linklocal=0
fi
}
The condition for this code getting called is weird. It would
require ipv6_enable="no" (which is default)... yet it goes and
tinkers with ipv6 sysctls anyways. I assume that the idea behind
ipv6_enable is that it's ONLY set to "yes" by administrators who
want to do IPv6-related things. (My point: It's bad to try and
set IPv6 sysctl when an administrator doesn't have ipv6_enable="yes")
This feature probably needs its own rc.conf option. Maybe this
is what the author had intended?
