Package: ucarp
Version: 1.2-1
Followup-For: Bug #264007
The attached patch allows configuration of ucarp via
/etc/network/interfaces; I think it's probably the sanest way of
configuring ucarp and allowing multiple interfaces while still fitting
in with the Debian way of doing things.

ucarp for Debian
----------------
-Check out the sample scripts in /usr/share/docs/examples for ideas on
-upscript/downscript usage.
+ucarp can be configured via /etc/network/interfaces. For example:
+
+iface eth0 inet static
+ address 10.0.0.2
+ netmask 255.255.255.0
+ ucarp-vid 3
+ ucarp-vip 10.0.0.1
+ ucarp-password 16charsatmost
+iface eth0:ucarp inet static
+ address 10.0.0.1
+ netmask 255.255.255.255
+
+will cause ucarp to be started when eth0 is brought up, using a vid of 3
+and a password of 16charsatmost with the virtual IP of 10.0.0.1. When ucarp
+determines that this host is the master eth0:ucarp will be brought up -
+you can use the normal pre-up/up stanzas in /etc/network/interfaces if you
+have extra things to do when the virtual IP comes up.
+
+You can also override the default up/down scripts
+(/usr/share/ucarp/vip-{down,up}) by using the ucarp-upscript and
+ucarp-downscript options. Note that you must ensure your scripts take
+care of bringing the VIP up and down if you do this.
