Looks like my original post did not come through for some reason. Maybe it was too long.

Here's the most important example from the original post. It works as-is. 
If I uncomment the commented "up" and "down" lines, everything breaks. 
Yes, I have real numbers and not nnn in the real config file.:

allow-hotplug eth0
iface eth0 inet static
        address nn.nnn.179.107
        netmask 255.255.255.224
        broadcast nn.nnn.179.127
        gateway nn.nnn.179.97
        up ip addr add nn.nnn.179.108/27 broadcast nn.nnn.179.127 label eth0:1 dev eth0
#        up ip addr add nn.nnn.179.109/27 broadcast nn.nnn.179.127 label eth0:2 dev eth0
        down ip addr del nn.nnn.179.108/27 label eth0:1 dev eth0
#        down ip addr del nn.nnn.179.109/27 label eth0:2 dev eth0
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 192.168.0.8 192.168.0.16

Thanks,
