Maybe "bash --version" would be more reliable than uname?
If you do something like that, then you may as well do
$ file /bin/ls
Not too useful either ...
bash --version GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0) Copyright (C) 2007 Free Software Foundation, Inc. file /bin/ls /bin/ls: Mach-O universal binary with 2 architectures /bin/ls (for architecture x86_64): Mach-O 64-bit executable x86_64 /bin/ls (for architecture i386): Mach-O executable i386
However ... this discussion was already being held long ago ... there is no reason why luatex could not be as smart as "bash --version" is and aware of the architecture it was compiled for (that is not necessary the platform it is running on; an obvious case being i386 luatex running on 64-bit Mas OS X for example). Somebody would have to write some simple code to check for that though. Mojca
