Remember that rc.conf follows shell syntax and sematics, so the second =
_alias0 and _alias1 will overwrite the previous ones.

In 9.0 you can use the ipv4_addrs_<ifname> variable to set both the IPv4 =
"main" address as well as "alias" addresses, see rc.conf(5).  There =
doesn't seem to be an equivalent IPv6 option, as best as I can tell.
