on a 5000/25 and 5000/20:

     filename "netbsd.ecoff"  ;
     # Warning! Some proms (KN02-CA v2.0m PROM) fail to get an IP
     # address if option  root-path has a string of >= 16 chars.
     # Use symlinks to keep the root-path <= 15 chars.
     # OK:        option root-path "xxxxyyyyzzzzaaa";
     # TOO LONG:  option root-path "xxxxyyyyzzzzaaaf";
     # ALSO TOO LONG: option root-path "/export/nfsclient/pmax-root" ;
     # OK ALTERNATIVE:  
     #   (after doing "ln -s /export/nfsclient/pmax-root /pmax-root")
     option root-path "/pmax-root" ;

On that machine, 15-char pathnames works, 16-char pathnames don't.
Maybe it depends on PROM versions?
