Hi. I note that we have $?OS, $?VM, and $?DISTRO (and their $* counterparts). I'd like to recommend that we eliminate $?OS, and replace it with $?KERNEL (ie. Linux) and maybe $?ARCH (ie. i386). Thoughts?

I disagree.

User-space code cares much more deeply about the operating system than the kernel, largely thanks to libc or the equivalent. For example, BSD systems can be built on a number of different kernels. Mac OS X is in principle FreeBSD on Mach, but there are a huge number differences from "plain" FreeBSD that have nothing to do with Mach. Instead, it would be even more useful to represent $?OS.family, $?OS.version.major, $?OS.version.minor, etc. Linux distros often support switching kernel versions out from under the OS.

        So how about we define things as follows for Mac:
-       Kernel = FreeBSD
-       Arch = Mach
-       Distro = Mac OS X

        Would that work for you?

I agree we need versioning. My plan would be that each of these variables contain a name and a version, at the least. I also may not have been clear on the fact that I wanted to retain Distro.

        Anyway, does this help some?
