i have compiled a custom kernel on a non mission critical machine, but since the kernel is not working like i would, how can i mannualy remove the kernel?

and second is, in debian i used to compile kernels as installable packages, that could easily be installed on another machine, how can i do this in open suse?

Make sure you know the exact name of that kernel, then delete the
corresponding “/lib/modules/” trees. Also the corresponding files in
/boot, and the /usr/src.

But before that, make sure that you have another kernel installed and
that it boots.

“make rpm”?

So normally you remove kernels using YaST but that does not work if you did a manual compile outside of YaST. You failed to mention your openSUSE version used. To delete a manually compiled kernel you would remove the folder you did this in and these two others:

  1. Delete the /lib/module/version-desktop folder and the kernel modules: 1.7 GB (Must be root to remove)
  2. Delete three files in the /boot folder: 21 MB, called initrd-version, System.map-version & vmlunuz-version (Must Be root to remove)

I have a blog on compiling kernels you can use and include links to three bash scripts I have written to compile, remove and fetch any kernel version, past or present.

Thank You,
