The first thing to note is that the kernel tries to insert modules
for non-existent network protocols by calling modprobe with net-pf-N
where N is the protocol number. N=10 for IPv6.

... because the module is now known as ipv6 not net-pf-10.

You've made two changes at the same time - no wonder you're getting
confused. In the first change, you've told it to no longer alias
net-pf-10 to ipv6, so it won't go anywhere near "ipv6" anymore. In
the second change, you've told it to use /bin/true to insert the ipv6
module - which it doesn't find because its still looking for "net-pf-10"

Golden rule: only make one change at a time.

Here's the practical examples showing what's going on:

[root@cps /root]# cat /etc/modprobe.conf
[root@cps /root]# modprobe net-pf-10
FATAL: Module net_pf_10 not found.
[root@cps /root]#

---

[root@cps /root]# cat /etc/modprobe.conf
alias net-pf-10 ipv6
[root@cps /root]# modprobe net-pf-10
FATAL: Module ipv6 not found.
[root@cps /root]#

---

[root@cps /root]# cat /etc/modprobe.conf
alias net-pf-10 ipv6
install net-pf-10 /bin/true
[root@cps /root]# modprobe net-pf-10
FATAL: Module ipv6 not found.
[root@cps /root]#

---

[root@cps /root]# cat /etc/modprobe.conf
alias net-pf-10 ipv6
install ipv6 /bin/true
[root@cps /root]# modprobe net-pf-10
[root@cps /root]#
