genkernel

Gentoo Linux utility to compile and install kernels. More information: https://wiki.gentoo.org/wiki/Genkernel.

• Automatically compile and install a generic kernel:

sudo genkernel all

• Build and install the bzImage|initramfs|kernel|ramdisk only:

sudo genkernel {{bzImage|initramfs|kernel|ramdisk}}

• Apply changes to the kernel configuration before compiling and installing:

sudo genkernel --menuconfig all

• Generate a kernel with a custom name:

sudo genkernel --kernname={{custom_name}} all

• Use a kernel source outside the default directory /usr/src/linux:

sudo genkernel --kerneldir={{path/to/directory}} all
