I have built hundreds of kernel rpm packages, and all the documentation that I have read says to never build kernels as root. Yet that is what you indicate here. Can you explain? Thanks.

# dracut -f /boot/initramfs-$(uname -r).img $(uname -r)

or just type kernel version instead,

# dracut -f /boot/initramfs-4.19.163.img 4.19.163

to rebuild initramfs and avoid boot failures.

@Manoj,

I never upgrade kernels, unless any specific application requires a specific kernel version.

Regular security updates are enough to keep our system safe from vulnerabilities.

Here we are doing this kernel upgrade using ELRepo (kernel-ml), the main intention here is to keep the Linux box safe from all the latest vulnerabilities.

I google and found that people also do security updates using yum, so my question is do we really need to upgrade the kernel from 3.10 to 5.4 using kernel-ml of ELRepo or just doing security update using yum to existing stable kernel us enough?

just need your valuable suggestion, as you must have come across such experience

Manoj Raul
