perhaps this is non-essential when working with aliases, but i have
found the best and most predictable results come with using 'alias' at
the end.
eg instead of:
$ sudo ifconfig carp1 alias 123.32.217.21 netmask 255.255.255.0
use:
$ sudo ifconfig carp1 123.32.217.21 netmask 255.255.255.0 alias
perhaps my stigma for using alias at the end comes from mixing up
the 'delete' command for use with aliases and trying things like
$ sudo ifconfig carp1 delete inet 192.168.5.4 alias
instead of just doing
$ sudo ifconfig carp1 inet 192.168.5.4 -alias
to subtract the alias out.
i tried your ifconfig add and it seems to work OK for me:
---
carp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
description: LAN(sis0)
carp: MASTER carpdev sis0 vhid 14 advbase 1 advskew 1
groups: carp
inet 192.168.2.30 netmask 0xffffffe0 broadcast 192.168.2.31
inet 192.168.5.5 netmask 0xffffff00 broadcast 192.168.5.255
inet 192.168.6.5 netmask 0xffffff00 broadcast 192.168.6.255
inet 192.168.7.5 netmask 0xffffff00 broadcast 192.168.7.255
inet 192.168.8.5 netmask 0xffffff00 broadcast 192.168.8.255
inet 192.168.9.5 netmask 0xffffff00 broadcast 192.168.9.255
inet 123.32.217.21 netmask 0xffffff00 broadcast 123.32.217.255

and i can remove it OK with
$ sudo ifconfig carp1 123.32.217.21 -alias
without disturbing the rest of them. ( didn't need 'inet', but
tbh it makes me feel dirty to not type it in in these cases ).
there *is* a little difference between the syntax in hostname.if files
and commandline ifconfig. since 'alias' and '-alias' are parameters,
according to ifconfig(8), see if your result is any different if you
religiously adhere to the:
---
ifconfig [interface] [address_family] [address [dest_address]]
[parameters]
---
in the synopsis.
since i have made an effort to do so, i have never had an unexpected
result while using ifconfig - whereas previously i had made awesome
maneuvers like, while trying to remove an alias on an iface, actually
removing the IP i was logging into via.... etc.
