PHP's configure script has something similiar. At the end of the
configure it creates a config.nice script. So when you are upgrading
you just have to run ../php-4.0.whatever/config.nice and it configures
your new sources exactly like the old. Maybe this is a feature that is
dependant on the version of config that the developers use. I haven't
had the need to play with these packages for any of my projects yet.

I'm afraid I must disagree. If there were no such thing as upgrading,
then
when I install a new version of a package (after removing the old, of
course -- unless it is designed so that the two versions do not conflict
with each other) all of the data created/managed/whatever by the old
version would be lost (due to removal) and/or obsolete (due to different
software installed).
Any time the manufacturer of a product (software or hardware) alters the
product to raise its quality (or extend its life) that is an upgrade by
definition (check Webster's if you disagree).
And in fact, it turns out that what I asked for *almost* exists already
(in
config.status). And now I'm going to suggest a minor improvement to
configure that will hopefully make its way to people who might implement
it:
****************************
It would be great if (a) configure recorded the options used to build a
package in a format it [configure] could reuse and (b) there were a
command
line option to tell configure to read those options from a specific file
and/or directory. For example, instead of manually entering all of the
options (and hoping they match what was used for the previous version)
we
could enter a command something like this:
./configure --use=../vpopmail-4.9/config.opt
Then, any additional options could add (or replace) options from the old
file.
****************************
I doubt that this would be difficult to implement, especially for the
kind
of script guru that created configure in the first place. However, it
could be of great benefit quite often.
OK, 'nuf said.
