 Without prefix keyword, the name of the images used during archiving with the -p option will be used (they may differ). If -p wasn't used then the name mondorescue-1.iso, ... will be used.
 
-During boot mondorestore will start your NFS configuration and mount mondo's content from the network rather than from a physical media. You may alter the IP configuration stored from the original machine by passing the ipconf option describing respectively the IP address, netmask, broadcast and default gateway you want to setup for the machine, separated by ':'. Or alternatively, you may specify the dhcp keyword so that a DHCP request is made to get those information. In the 2 cases, you have to mention on which physical interface those parameters should apply. On some configurations, you may also want to increase the number of ping queries made before the NFS mount, which is of 3 by default, using the ping option and give the number you want.

If you have a different NFS server for the deployment than for the archiving, you can also precise it through the nfsmount option. The structure on both server under the mountpoint has to be the same.
