If you have a source code distribution where you rename an element during the build (thanks NI for this setting), linked mnu files (also part of the build) should be relinked to the new names.
If you take for instance an foo.lvlib that contains an palette file and you rename the foo.lvlib to foo__prod.lvlib, all the items on the palette will be searching for foo.lvlib:blah.vi instead of foo__prod.lvlib:blah.vi.
