+ boot cds, however, will initially look for a file named 'plnode.txt' on
+ either a floppy disk, or burned onto the cd itself. Alternatively, it
+ will fall back to looking for the original file name, 'planet.cnf'. This
+ initial file reading is performed by the boot cd itself to bring the

+ of and read in the file, so it can get the extra fields not initially
+ used to bring the network online (node_key and node_id). Below is the
+ search order that the boot manager will use to locate a file. If a file
+ is found in the order below, but does not match the network that has
+ already been setup, then there may be two configuration files located on
+ the same machine. In this situation, the file is skipped and searching
+ resumes.</para>
