Here's an excerpt from /etc/cond.d/net
ifconfig_eth0=(
        "10.0.37.5 broadcast 10.0.37.255 netmask 255.255.255.0"

#       "192.168.0.175 broadcast 192.168.0.255 netmask 255.255.255.0"
#       "192.168.0.3 broadcast 192.168.0.255 netmask 255.255.255.0"
#       "192.168.0.4 broadcast 192.168.0.255 netmask 255.255.255.0"
)
ifconfig_eth1=(
        "10.0.33.124 broadcast 10.0.33.255 netmask 255.255.255.0"
)
alias_eth0=(
       "10.0.37.4 netmask 255.255.255.0"
)

# This is just like setting the gateway config option in the old-style iface
# config, but allows one to add custom routes.  This should not be needed if you
# are obtaining an address via DHCP since the default route should be set
# automatically.
routes_eth0=(
        "default gw 10.0.33.250"
)

What I think should be happening.
up eth0 on the 37 network
up eth1 on the 33 network
set default route

What's happening instead
up eth0 on the 37 network
default route creation fails 33 network not reachable
up eth1 on the 33 network

The alias is not getting created at all.  How can I re-order these events to allow the default route to be set properly.
