Good point. Source RPM handles this with options you can pass to the rpmbuild command. Maven could have either command line or configuration options to do the same.
From http://www.rpm.org/max-rpm-snapshot/s1-rpm-multi-build-install-detection.html , "The *--buildarch* and *--buildos* options can be used to set the build-time architecture and operating system rather than relying on RPM's automatic detection capabilities. These options are added to a normal RPM build command. One important point to remember is that, although RPM does try to find the specified architecture name, it does no checking as to the sanity of the entered architecture or operating system. For example, if you enter an entirely fictional operating system, RPM will issue a warning message, and then happily build a package for it." This brings up an interesting idea. Rather than building the infrastructure into Maven to detect OS and architecture information, perhaps Maven could delegate this to rpm, at least on Linux. RPM is the package format defined for the Linux Standard Base, although it mentions the standard includes only the rpm package format and not the rpm command or specific rpm macros. In practice, this might not be a big deal. Most or all distros might use the same rpm command options and a small set of standard macros. http://www.linuxbase.org/spec/refspecs/LSB_1.2.0/gLSB/swinstall.html http://www.linuxbase.org/talks/lca2005/img52.html Just an idea for trying to reduce the effort to support this and unnecessary duplication of functionality.
