# About the Kernel
Not Written.
## Generate symlink
```
#Generating a symbolic relative link to the "last" kernel :
ln -r -s ./vmlinuz-5.2.13-desktop-2.mga7 ./vmlinuz
rm -f ./vmlinuz && ln -r -s ./vmlinuz-5.3.1-desktop-2.mga7 ./vmlinuz
```
## Commands used :
./create_arm_image.sh --clean --config bananaPro --build-path ./build
./create_arm_image.sh --all --target bananaPro --size 2 --tainted --nonfree --build-path ./build --config bananaPro 2>&1 | tee -a ./log/creation.log
