Tried it again, it just breaks the boot. After a lot of firefighting found that elrepo kernel-lt doesn't have `xfs` in initramfs image and it fails mounting the lvm which uses xfs
# lsinitrd /boot/initramfs-4.18.0-240.1.1.el8_3.x86_64.img | grep xfs.ko -rw-r--r-- 1 root root 442760 Aug 11 2020 usr/lib/modules/4.18.0-240.1.1.el8_3.x86_64/kernel/fs/xfs/xfs.ko.xz Tested kernel-ml and it has the needed xfs module After installing the new kernel, I needed to copy over the "options" line from /boot/loader/entries/ovirt*.conf to the new one. Hope this saves a lot of hair pulling for someone.
