Modifying map names and aliases
Because of file naming conventions, names of existing NIS maps
may conflict with names you want to use for another map or another file.
To avoid conflicts, you can assign an alias.
If this does not work,
use a different name for the newer file to avoid having to change
the name of an existing map.
If you must change the name of an existing map, follow this procedure:
If you are going to use the old name for a different NIS map, remove the old map from the master server; create and propagate the new map, using the old name. You will not need to add the name to the YP_MAP_X_LATE files on all NIS servers because it is already there.
