booted old kernel when new one is available

[pbrezina]

It looks like bootc boots the old kernel when upgraded package is already available.

I run dnf upgrade in the Containerfile and new kernel is installed into the image. But bootc upgrade && sudo reboot still loads the old image. It looks like additional image rebuild and bootc upgrade is needed to pick up the updated kernel. Is there any way to start with the latest kernel immediately? Or is this a bug?

[pbrezina /var/home/pbrezina]$ rpm -q kernel
kernel-6.12.7-200.fc41.x86_64
kernel-6.12.8-200.fc41.x86_64
[pbrezina /var/home/pbrezina]$ uname- r
bash: uname-: command not found
[pbrezina /var/home/pbrezina]$ uname -r
6.12.7-200.fc41.x86_64

You can't have multiple kernels in a bootc image, only one. I would avoid RUN dnf upgrade in a container build today.
