Also affects Red Hat Enterprise Linux 6.

+++ This bug was initially created as a clone of Bug #610301 +++

Description of problem:
The spec file for the ghostscript package creates the following
three files in /etc/ghostscript/8.71:
  cidfmap.local
  CIDFnmap.local
  Fontmap.local

The files under /etc/ghostscript are important because they are
the only ones marked as %config(noreplace), and so if you make
customizations to the system-wide files in
/usr/share/ghostscript/8.71/Resource/Init, they may be clobbered
if the upstream version of the file changes.

The system-wide cidfmap and CIDFnmap files contain lines like
these at the end:

% must be at the bottom of line to allow people overriding everything.
(cidfmap.local) .runlibfileifexists

% must be at the bottom of line to allow people overriding everything.
(CIDFnmap.local) .runlibfileifexists

No such line exists at the end of the global Fontmap file.  As a
result, making customizations in the obvious place (the
/etc/ghostscript/8.71/Fontmap.local file that the package helpfully
creates for you) results in your customizations never being read
in by gs.

Version-Release number of selected component (if applicable):
8.71-6.fc11.x86_64, 8.71-9.fc13.x86_64, and presumably also the
current versions in F12 and Rawhide

Steps to Reproduce:
1. yum install ghostscript strace
2. strace gs >/tmp/gstrace 2>&1
3. search for Fontmap in /tmp/gstrace with your favorite editor
   and note that several locations including /etc/ghostscript and
   /etc/ghostscript/8.71 are searched for a file called Fontmap,
   but Fontmap.local is never tried
  
One way to tackle this would be to patch the upstream Fontmap
file to add something like this to the end of the global file:
(Fontmap.local) .runlibfileifexists
I recommend this solution.

Another approach would be to discontinue creating the
/etc/ghostscript/8.71/Fontmap.local file and instead create
one named Fontmap.  However, all systems with ghostscript
already installed may still have the Fontmap.local file present
and be confused when they try to use it.

--- Additional comment from twaugh on 2010-09-03 06:58:04 EDT ---

The patch to get ghostscript to read Fontmap.local was dropped after ghostscript-8.15.4-3.fc7.  I think that was just a mistake at the time -- those files were reorganised upstream.

Thanks for reporting it.
