+=== 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
+....
