+===== Introduction =====
+You might have to tweak some things to make Linux clone nicely.  Update this document as needed.
+==== Taking the hostname from DHCP ====
+RHEL/Fedora does this by default.  Ubuntu/Debian respects the /etc/hostname set at install time over DHCP.  To fix this, just delete /etc/hostname.
+==== Turning off persistent eth devices ====
+Some Linux distributions try to keep track of which ethernet device is which by MAC address.  This is bad for us, because when cloning, it will assume that eth0-1 were "removed" (since they aren't on the destination machine), and therefore use eth2-3.  This screws things up, so we need to turn it off.  The basic strategy is to remove MACs from existing config files and possibly turn off the feature that put them there in the first place.
+=== Ubuntu/Debian ===
+Edit "/etc/udev/persistent-net-generator.rules" and add the following to the top:
+<file>
+# hack: turn ethernet persistance off
+GOTO="persistent_net_generator_end"
+</file>
+Next, edit "/etc/udev/rules.d/z25_persistent-net.rules" (or similar) to remove MAC addresses already stored.  Delete all uncommented lines.  If you can't find this file, search all of /etc for files that contain your current MAC:
+<file>
+ # ifconfig
