2007-10-28 Thread Josip Rodin
Hi, Is there any reason why the kernel makefiles don't support the 'install' target on sparc, just like they do on x86(_64)? The standard installkernel(8) wrapping works fine. I posted this question a while ago to the debian-sparc list[1] and Martin Habets replied with a fairly trivial patch[2],
