confLNOPTS
Switches for the program to link files Build macro
As part of installing the
sendmail suite of programs,
some symbolic links have to be established. The
program to create those symbolic links is usually
called ln(1), but it can be
renamed with the confLN macro described in the previous
section.
The default arguments given to the program are
-f -s followed
by the name of the file to symbolically link. You
can change those arguments by using this confLNOPTS
Build macro:
define(`confLNOPTS', `-s')
Here, we removed the -f switch, which forces an
unconditional link. Another use for this confLNOPTS
Build macro would be to devise
arguments for a different or custom linking program
(see the previous section).
