But you are removing perfectly valid code. Don't do this!!
Just read the documentation (especially Documentation/nfsroot.txt)
and pass the CORRECT boot arguments, which in case or several network
interfaces MUST specify which interface to configure, i. e. the
minimum information is then
... ip=10.32.5.17:10.32.5.15::255.255.0.0:bug:eth0:off
[Note that your "ip=" string has one colon too many, too.]

Software suppliers are trying to make their software packages more
``user-friendly''. . . . Their best approach, so far, has been to
take all the old brochures, and stamp the words, ``user-friendly'' on
the cover. - Bill Gates
