# Linux Kernel Module Cheat
The perfect emulation setup to study and develop the <<linux-kernel>> v5.9.2, kernel modules, <<qemu-buildroot-setup,QEMU>>, <<gem5-buildroot-setup,gem5>> and x86_64, ARMv7 and ARMv8 <<userland-assembly,userland>> and <<baremetal-setup,baremetal>> assembly, <<c,ANSI C>>, <<cpp,C++>> and <<posix,POSIX>>. <<gdb>> and <<kgdb>> just work. Powered by <<about-the-qemu-buildroot-setup,Buildroot>> and <<about-the-baremetal-setup,crosstool-NG>>. Highly automated. Thoroughly documented. Automated <<test-this-repo,tests>>.

### 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
