Bug 2035939

.Certain network interfaces and IP addresses can be excluded when creating a rescue image You can use the `EXCLUDE_IP_ADDRESSES` variable to ignore certain IP addresses, and the `EXCLUDE_NETWORK_INTERFACES` variable to ignore certain network interfaces when creating a rescue image. On servers with floating addresses, you need to stop the ReaR rescue environment from configuring floating addresses that are moved to a fail-over server until the original server is recovered. Otherwise, a conflict with the fail-over server would occur and cause a consequent disruption of the services running on the fail-over server. To prevent conflicts, you can perform the following actions in the ReaR configuration file `/etc/rear/local.conf`: * exclude the IP addresses in the ReaR by providing the `EXCLUDE_IP_ADDRESSES` variable as a bash array of addresses. For example: `EXCLUDE_IP_ADDRESSES=( 192.0.2.27 192.0.2.10 )`, * exclude the network interfaces in the ReaR by providing the `EXCLUDE_NETWORK_INTERFACES` variable as a bash array of interfaces. For example: `EXCLUDE_NETWORK_INTERFACES=( eno1d1 )`.
