  1. 0 Unnamed devices (e.g. non-device mounts)
  2. 0 = reserved as null device number
  3. See block major 144, 145, 146 for expansion areas.
  4. 1 char Memory devices
  5. 1 = /dev/mem Physical memory access
  6. 2 = /dev/kmem OBSOLETE - replaced by /proc/kcore
  7. 3 = /dev/null Null device
  8. 4 = /dev/port I/O port access
  9. 5 = /dev/zero Null byte source
  10. 6 = /dev/core OBSOLETE - replaced by /proc/kcore
  11. 7 = /dev/full Returns ENOSPC on write
  12. 8 = /dev/random Nondeterministic random number gen.
  13. 9 = /dev/urandom Faster, less secure random number gen.
  14. 10 = /dev/aio Asynchronous I/O notification interface
  15. 11 = /dev/kmsg Writes to this come out as printk's, reads
  16. export the buffered printk records.

  21. ...
  22. 250 = /dev/initrd Initial RAM disk
  23. Older kernels had /dev/ramdisk (1, 1) here.
  24. /dev/initrd refers to a RAM disk which was preloaded
  25. by the boot loader; newer kernels use /dev/ram0 for
  26. the initrd.

  32. Pseudo-tty's are named as follows:
  33. * Masters are "pty", slaves are "tty";
  34. * the fourth letter is one of pqrstuvwxyzabcde indicating
  35. the 1st through 16th series of 16 pseudo-ttys each, and
  36. * the fifth letter is one of 0123456789abcdef indicating
  37. the position within the series.
  38. These are the old-style (BSD) PTY devices; Unix98
  39. devices are on major 128 and above and use the PTY
  40. master multiplex (/dev/ptmx) to acquire a PTY on
  41. demand.
