You are extending the NIS support in your network to include a new NIS map to support automount direct maps. As part of this process, you modify the NIS Makefile to include the following line:
auto.direct.time: $(DIR)/auto_direct
What does this line signify?

A.
The auto.direct.time file can be found in the $(DIR)/auto_direct directory.

B.
The auto.direct.time file is created by copying the $(DIR)/auto_direct file.

C.
Any reference to the file auto.direct.time should use the contents of the $(DIR)/auto_direct file.

D.
For the auto.direct.time dependency to succeed, the $(DIR)/auto_direct file must exist.
