+%description
+UCARP allows a couple of hosts to share common virtual IP addresses in order
+to provide automatic failover. It is a portable userland implementation of the
+secure and patent-free Common Address Redundancy Protocol (CARP, OpenBSD's
+alternative to the patents-bloated VRRP).
+Strong points of the CARP protocol are: very low overhead, cryptographically
+signed messages, interoperability between different operating systems and no
+need for any dedicated extra network link between redundant hosts.

+
+# UCARP daemon by default uses the first PCAP-capable interface as returned by
+# pcap_lookupdev(), this is often "eth0". This option allows you to change
+# this behaviour.
+BIND_INTERFACE="eth0"
+
+# This is a mandatory option. UCARP daemon will use this IP address for its
+# announces regardless of the addresses actually assigned to the interface.
+#BIND_ADDRESS="10.0.0.2"
+
+# There is a simple and an advanced way to configure UCARP. In both ways you
+# have two physical routers with distinct IP addresses on the same IP network.
+
+# In the simple scenario, you want a single virtual IP address from the _same_
+# network to be taken over by one of the routers. You configure this VIP right
+# here then:
+#VIP_ADDRESS="10.10.10.10"
+
+# In the complex scenario, your virtual router consists of more than one IP
+# address. For example, you might want to assign to the virtual router not only
+# the address which is used as the default gateway on the LAN, but also the only
+# real IP address, which you got from your ISP. Your configuration would have
+# two steps then:
+# 1. Configure the VIP_ADDRESS to "255.255.255.255"
+# 2. Create a file in the same directory which holds vip-XXX.conf, with a name
+# vip-XXX.list. For example, if the .conf file is named vip-001.conf, the .list
+# file would be vip-001.list. Each meaningful line of this file will be used as
+# an argument for "ip address add" and "ip address del" commands. This way you
+# can control, which IP addresses will be assigned to which interfaces.
+#VIP_ADDRESS="255.255.255.255"
+
+# If you have extra options to add, see "ucarp --help" output
+# (the lower the "-k <val>" the higher priority and "-P" to become master ASAP)
+# Please note you can use only the following options here:
+# --preempt (-P): becomes a master as soon as possible
+# --neutral (-n): don't run downscript at start if backup
+# --advbase=<seconds> (-b <seconds>): advertisement frequency
+# --advskew=<skew> (-k <skew>): advertisement skew (0-255)
+# The rest of options list is built up by the UCARP initscript.
