I like to install a realtime kernel into the volumio (x86) package, this is what I did until now:
- Edited /etc/apt/sources.list and added: “http://security.debian.org/debian-security jessie/updates main”
- rmdir /var/tmp # to increase the /var/tmp volume
ln -s /tmp /var/tmp
- sudo apt-get update
- sudo apt-get install linux-image-4.9-rt-686-pae
Now I have in /boot:
But volumio still boots the original system.
Any idea what I have to do next to make the realtime kernel boot at system start?
