- 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 of the default directory `/usr/src/linux`:
