Good idea, the ipv4_ifconfig was just a placeholder more ore less. But
why is there a differentiation between adding the first ipaddr. to the
interface and adding anoter one anyway?

Part of my idea (not implemented in this piece of code) was to use
ifconfig_if (or ifconfig_if_option) for interface options only and use
ipv4_ and ipv6_ifconfig_if to configure the ipaddr. of the interface.
This would make no difference between adding the first ipaddr and adding
more. Just for the record ;-).

I moved everything to ifalias_up() keeping the other aliasN stuff.

Done.

Yes and /etc/defaults/rc.conf also.
