Question

How can I boot my compiled kernel image on Gentoo?

Posted February 3, 2013 21.6k views
Hi, I've successfully compiled a custom kernel image on Gentoo x64, but grub menù doesn't seem to show up at boot, so I can't choose my kernel. I think this is an important task to solve. Kernel should be kept up to date to prevent security and bug issues, also standard kernel is not compatible with an up to date gentoo, since latest stable udev needs a kernel option which is disabled by default: result is no network at next reboot after upgrade. thanks

Hey @otto and @nuvui3j439v3n93 - you can actually run a custom kernel on some distributions at DigitalOcean!

Currently, the following are supported:

  • Debian 8
  • Ubuntu 15.04
  • Ubuntu 15.10
  • Fedora 23
  • FreeBSD

With the release of Ubuntu 16.04, an LTS distribution with build in kernels will be available.

We do not offer booting from custom kernels at the moment. This is in the works and you can follow its progress here: https://digitalocean.uservoice.com/forums/136585-digital-ocean/suggestions/2814988-give-option-to-use-the-droplet-s-own-bootloader-

However, we will be updating our Gentoo/Arch images this week.

yes please, same issue here. i cant run gentoo because udev is not compatible. the current gentoo installacion is more than 2 years old, wich a such outdated kernel. its unusable at the moment :/

We are working on providing a way for customers to either boot custom kernels or to be able to select from a list of supported kernels which we will maintain.

We hope to have the first beta of this available to the public in late February or early March.

Any news about updated kernel images? Was supposed to be in place last week, just had a reboot but still on 2.6.39 with no udev support.
Do I need to create a new droplet?

This is a huge issue. I've been fighting for the past few hours trying to figure out why I can't seem to either load a 3.X kernel or get SELINUX enabled on a Debian droplet. It's quite frustrating to finally realize that I'm not ALLOWED to run a different kernel, even if grub is correctly configured. Is there a technical reason that this is not being allowed?

so...basically you have created a "Gentoo 2013-1 x64" image, but is just the same as the old one. I was expecting this to be a 2013 release but its the 2008 one, plus i wasted my time reviewing this.

...why ?

Also blocked by not being able to run a custom kernel. It's pretty important on Linux, not just for gentoo, but for many serious uses which require recent kernel features.

This sucks. Get your act together. Lots of other virtualisation providers allow this just fine.
