When we tried to download Oracle Linux ISO, we saw 2 boot ISO images, the first one is "Boot ISO", the other is "UEK boot ISO". Which one should we download? What's the difference?
- Boot ISO
- UEK boot ISO
It contains the original Red Hat kernel. This is because Oracle Linux is also one of Red Hat Enterprise Linux (RHEL) derivatives.
It contains Oracle developed kernel called Unbreakable Enterprise Kernel (UEK) instead of the original Red Hat kernel.
That's the difference.
In fact, if you're looking for the minimal installer of RHEL distributions, you may choose AlmaLinux. It packages a minimal ISO image for download, the file size is acceptable.
