Cosider something like the following:
~/bk/linux-2.5 ~/compile/arm <= Used to check that the kernel compiles for ARM ~/compile/allmod <= My config with a lot of modules ~/compile/machine <= The config I use on my machine ~/compile/work <= That's my sandbox
All configurations share the same src. During the last copule of days we have seen some header file clean-ups. It would have been nice if they tried compiling in all four configurations listed above. But if I switch .config then it is often a recompile of everything, whereas the above setup can minimize it. The header file cleanup is maybe not the best example because touching a few key header files requires recompilation of everything anyway.
But my point is that there is a good use of different configurations based on the same src.
Others that have asked for separate obj dir may step in here, explaining why they thougt it was good.
