[Arm-dev] update-boot?

The wiki says:

Before centos-userland-release-7-5.1804, in order to activate the new 
kernel and edit /boot/extlinux/extlinux.conf, you had to run 
/usr/bin/update-boot. This is no longer valid and it is done 
automatically by grubby.

But I just happened to look at /boot/grub/grub.conf

default=0
timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title CentOS-Userland-7-armv7hl-generic-GNOME-1804 
(4.14.28-201.el7.centos.armv7hl)
         root (hd0,1)
         kernel /vmlinuz-4.14.28-201.el7.centos.armv7hl ro 
root=UUID=be2c9311-e289-4cab-b878-89b522144d70
         initrd /initramfs-4.14.28-201.el7.centos.armv7hl.img

And I did the yum update that installed the 4.14.52 kernel.

Should I run update-boot?

/boot/klist.txt has:
4.14.28-201.el7.centos.armv7hl
4.14.52-201.el7.armv7hl
