- don't make device files since we are in the DEVFS era.
(for the last resort, fixit.flp still has /dev/MAKEDEV.)
- increase FIXITINODE size to 10 times (40000).
After this change, we have 42kbytes of free space, and 38
of free inodes (confirmed with 5.0-CURRENT-20020327-JPSNAP).
Since 4-stable doesn't have DEVFS, we can't MFC this (except FIXITINODE).
