1. Please do a backup even the script doesn't plan to ruin anything critical.

2. If you choose wrong board you might end up with not bootable system.

3. We are going to remove current kernel package together with headers, firmware and board definitions.

4. The script will also conduct apt-get upgrade so all packages will be upgraded.

5. Where possible you can upgrade/downgrade kernel from legacy to vanilla and vice versa.

6. The whole process takes at least 8 minutes on a fresh image to 30 minutes if you upgrade from other system.

7. You might need to power cycle the board.
