Sorry about that.  I was trying various quoting schemes I'd found in
examples.

My current configuration works:

  modules_eth0=( !plug )
  config_eth0=( "192.168.8.4/16" )
  routes_eth0=( "default via 192.168.0.254" )

  modules_eth1=( !plug )
  config_eth1=( "10.0.0.1/8" "192.168.250.1/24" )

$ /sbin/ip address show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:1b:21:b1:d1:e9 brd ff:ff:ff:ff:ff:ff
    inet 192.168.8.4/16 brd 192.168.255.255 scope global eth0
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:16:17:84:a7:b3 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.1/8 brd 10.255.255.255 scope global eth1
    inet 192.168.250.1/24 brd 192.168.250.255 scope global eth1
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 00:18:e7:08:20:33 brd ff:ff:ff:ff:ff:ff

  
And the lack of eth1:1 is presumably explained if the system is using
the iproute2 module instead of the ifconfig module.  My current theory
is that iproute2 is getting used because I have openvpn installed with
the iproute2 use flag. [I'm not actually using openvpn, but it's still
istalled from a couple years ago when I was using it.]

Yes, I know that the /24 subnet defined by the second eth1 address
overlaps the /16 subnet defined by the eth0 address. 

For historical reasons, 192.168.250.nnn is on eth1, and
192.168.everything-but-250.nnn is on eth0.

And eth2 is used only by a VM client OS.

Yea, it's a messy, but it's still easier than using 4 different
machines....
