[pkg-nvidia-devel] Bug#585695: nvidia-kernel-source: Manual built of module does not consider already set KVERS and KSRC environment variables

[Edgar Sippel]

Package: nvidia-kernel-source
Version: 195.36.24-1
Severity: important
Tags: squeeze

The latest change in debian/rules applies a new behaviour of the build script which makes manual building the module not working anymore according to documentation README.debian method #3:
I'm using several different kernels on my machine, and normally I build the nvidia packages for all of them by just setting the respective environment variables KVERS and KSRC to the different values and then building the modules one after another manually by calling /usr/src/modules/nvidia-kernel/debian/rules binary_modules.
The latest changes in version 195.36.24-2 do not consider these already set variables anymore but, as far as I understood the script takes the version from the target of /usr/src/linux, which, on my machine always points to the 'main' kernel, meaning the one currently in testing. So, compiling for different versions always needs a change of that symlink including the risk of letting this point to a wrong version afterwards when forgetting to re-set it.
Please, either update the documentation to give the user a hint why building does not work as he's used to or (preferrably) let the script check if these variables are already set and consider them.

Best regards,
Edgar
