Specifying only constrained options in /etc/libmap.conf ?

[Mark Stosberg]

I would like to use /etc/libmap.conf to apply some mappings
which only apply to the "darcs" executable.

However the man page for "libmap.conf" contains this warning:

 "WARNING!  Constrained mappings must never appear first in the configura-
 tion file.  While there is a way to specify the ``default'' constraint,
 its use is not recommended."

Warning aside, I thought what I would want is the following. Is
there a better way? I want to limit the scope of this change because
I'm not sure how it will affect the rest of the system, particularly MySQL.

[darcs]
libpthread.so.1 libthr.so.1
libpthread.so.2 libthr.so.2
libkse.so.3 libthr.so.3

Thanks for your help!
