I know it might sound crazy, but I was wondering if there is a way to
set the RPM package name at install time.
I figured out that I can set the package name dynamically at build time,
by doing this:
%define myprefix %(echo $MY_ENV_VAR)
and then set the package name like this:
Name: %{myprefix}_my_package
But after I build the RPM package file and run "rpm -qip
package_file.rpm" it shows the Name evaluated to the value set at build
time.
The purpose behind this exercise is to install the same package multiple
times with different names on the same server. (The reason the package
is being installed multiple times is because the scripts in the RPM
package do different things depending on the environment variable, and
we don't want to create multiple packages, and we want to avoid using
--dbpath.)
Why does it work for RPM built-in macros? For example, if on the build
machine my "%_usr" is "/usr" but on install machine my "%_usr" is set to
"/opt", how is it that it works?
Your help is appreciated.
