FYI Migrating nodes are not a problem for SVN Head, it uses
the GUID to identify the STB's and the recorders have the
smarts to use a new node and port if the device moves.

For 0.20 you are probably seeing an improvement because you
changed Linux kernels and hence have newer FireWire drivers.
You will still see nodes move if you add new devices to the
bus that your STB's are on. I did a lot of the testing for
the node tracking code by just plugging and unplugging a
hard drive into the back of the STB. Another fun thing to
do is plug a Mac and a PC (both running mythbackend on OSX
and Linux, resp) into the STB and having them fight over
control of the STB.
