Cute idea -- but it doesn't deal with the distro version, and it fails
for my machine (Fedora, but doesn't have "Fedora" in /proc/version so
it returns "redhat").

That's not a problem -- I just needed some hack for the build script,
not for creating installers.  (It's a nice idea -- have the installer
contain platform independent files in its embedded tgz, and sub
archives that have binaries for different platforms -- and when it's
run, detect the OS and unpack the right binaries.)

It would be nice if everyone would just standardize on something...

(I'm pretty lost when it gets to such Debian technicalities...)
