centos8删除开机菜单选项
升级内核后开机界面出现多个菜单选项，我的第一个选项并不能进入系统，须删除。
原因是：CentOS更新后不会自动删除旧内核。
首先查看内核版本：
(base) [root@localhost ~]# uname -a Linux localhost.localdomain 4.18.0-80.11.2.el8_0.x86_64 #1 SMP Tue Sep 24 11:32:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
查看系统中全部的内核RPM包
(base) [root@localhost ~]# rpm -qa|grep kernel kernel-modules-4.18.0-80.el8.x86_64 kernel-4.18.0-80.el8.x86_64 kernel-core-4.18.0-80.11.2.el8_0.x86_64 kernel-debug-devel-4.18.0-80.el8.x86_64 kernel-core-4.18.0-147.5.1.el8_1.x86_64 kernel-headers-4.18.0-147.5.1.el8_1.x86_64 abrt-addon-kerneloops-2.10.9-10.el8.x86_64 kernel-devel-4.18.0-80.el8.x86_64 kernel-modules-4.18.0-147.5.1.el8_1.x86_64 kernel-modules-4.18.0-80.11.2.el8_0.x86_64 kernel-devel-4.18.0-147.5.1.el8_1.x86_64 kernel-4.18.0-80.11.2.el8_0.x86_64 kernel-devel-4.18.0-80.11.2.el8_0.x86_64 kernel-tools-libs-4.18.0-147.5.1.el8_1.x86_64 kernel-tools-4.18.0-147.5.1.el8_1.x86_64 kernel-debug-devel-4.18.0-147.5.1.el8_1.x86_64 kernel-core-4.18.0-80.el8.x86_64 kernel-debug-devel-4.18.0-80.11.2.el8_0.x86_64
删除旧内核的RPM包

有些是不能随便删除的，比如下面的，4.3G的删了我就哭了
