38.8. Custom build directory
For now there is no way to change the build directory from out/ (resp. out.docker for <<docker>.) to something else.
However, if you just want to place the build storage in your hard drive and the source in your SSD, which is a good configuration if you are doing lots of builds, just create a symlink as:
mkdir -p /mnt/hd/linux-kernel-module-cheat-out ln -s out /mnt/hd/linux-kernel-module-cheat-out
