With HP-UX you can mount a NFS filesystem, so that the remote
device files are ignored. From the HP-UX MOUNT(1M) manual:

               .......  The nodevs option denies access to devices
               attached to the NFS client by causing attempts to read
               or write to NFS device files to return an error.

This option seems to me very useful to close certain security
holes. How can I get the same functionality on other unixes
especially under SunOS 4.1.1 ?
