deleting an old file during install

[Rick Macklem]

Hi,

With the NFS client switchover, the link to mount_nfs called
mount_newnfs is no longer used.

Can I just make an entry in
  head/ObsoleteFiles.inc
for this, so it is deleted during an install or is there a
better way?

Also, is it ok to do this without MFCing it, since it should
only apply to head?

Thanks in advance for any info, rick
