how hard is it to determine if it's an ipv6 vs ipv4 address? i suppose
that doesn't help you're using names instead of addresses.
it's a shame that /etc/ifaliases wasn't as flexible as the /etc/ifconfig.XXX
how about supporting /etc/ifaliases.XXX, with syntax of
family aliasaddress [optional parameters]
where optional parameters includes netmask, prefixlen, etc...
that doesn't help on the variable side (e.g $ifalias_XXX). however,
since you may have a number of aliases per interface, it would make
it tricky to support a variable number of args *and* multiple aliases
per interface in the one shell variable, so don't try and support
extending the $if* syntax in your rework.
