How to install RT Patch?

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: “ 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:

  1. vmlinuz-4.9.0-0.bpo.12-rt-686-pae
  2. initrd.img-4.9.0-0.bpo.12-rt-686-pa

But volumio still boots the original system.
Any idea what I have to do next to make the realtime kernel boot at system start?
Thanks Charly

Hi Charly,

I think you’re out on your own here on this, unless other intrepid RT kernel users want to step in and offer advice.

Thank you for your comment. Hopefully someone out there can help.

Hi Charly,
you cannot use your own kernel.
We have our own OS build based on jessie/ buster, our own initrd and our own grub.cfg, your install will not modify anything and you cannot do it manually either.
You’re at a dead end I’m afraid.
