At 8:30am I performed my first complete kernel build on Linux (2.6.37). I've had to repartition twice to get to this point, so I thought I'd post some advice. The kernel build (make rpm) used 5.3 G Byte of hard drive. This was on root (/), since I did not have any mount points in the path /usr/src/. This was openSUSE 11.4 and CONFIG_DEBUG_INFO was set to Y. Basically, I only made one change in make menuconfig, and that was the text to append to this build's name. Please plan accordingly for your specific build.
