Thanks very much for reply.
Now, we got a new disk and already formatted. We are trying to restore
whole thing to the new disk. (we have to replace the system boot disk). But
/dev/fd is not restored. When I am checking on the original disk, the
directory is always created by system:
# ls -l /dev/fd
total 0
crw-rw-rw- 1 root root 195, 0 Mar 19 17:58 0
crw-rw-rw- 1 root root 195, 1 Mar 19 17:58 1
crw-rw-rw- 1 root root 195, 10 Mar 19 17:58 10
crw-rw-rw- 1 root root 195, 11 Mar 19 17:58 11
crw-rw-rw- 1 root root 195, 12 Mar 19 17:58 12
crw-rw-rw- 1 root root 195, 13 Mar 19 17:58 13
...

Does that mean the /dev/fd can be ignored? When the new disk is in place
and reboot the system, this files under /dev/fd can be created?
Thanks!
