Build kernel

wget URL  # Download from kernel.org -> decompress
apt install git fakeroot build-essential ncurses-dev xz-utils libssl-dev bc flex libelf-dev bison
cp -v /boot/config-$(uname -r)* .config   # copiar el archivo de configuración a la carpeta descomprimida
- vim .config     # clean the value in the "CONFIG_SYSTEM_TRUSTED_KEYS" variable
make menuconfig   # leave default configuration #!! the optimization we can do it here
  # On the menu -> save and exit
make              # start compilation process
make modules_install
make install

# Indicar al boot loader que kernel queremos usar, debemos correr:
sudo update-initramfs -c -k 6.6.0  # version kernel 6.6.0 -> ya lo corrio el make, pero puede hacerse manualmente
sudo update-grub
