This was decreed but not agreed to.  I don't use devfs and don't plan
to use it until it works at least as well as specfs (if this is
possible).  I have noticed about 10 minor bugs in it despite only running
it to test it every 6 months or so.  Examples:
- file time updates are broken in several ways.
- stat() doesn't work right on devfs directories (st_size and st_blocks
  zero for all devfs files, but should be nonzero for directories).
- pathconf() doesn't work right on devfs directrories (_PC_NAME_MAX and
  _PC_PATH_MAX are unsupported, but must be supported for directories).
- acd devices still have insecure modes (world readable).
