My bad for leaving that off, but what about all the kernel* (like 4 rpms?) that normally gets installed? dtb-4.14.28-201.el7.centos.armv7hl initramfs-4.14.28-201.el7.centos.armv7hl.img System.map-4.14.28-201.el7.centos.armv7hl uImage-4.14.28-201.el7.centos.armv7hl uInitrd-4.14.28-201.el7.centos.armv7hl vmlinuz-4.14.28-201.el7.centos.armv7hl The dtb* is a directory.

For the YOLO approach yum remove $( rpm -q kernel | sort -n | head -n 2 ) That should work currently (though a safer method might be done)..
