CentOS如何刪除核心升級後多餘的啟動項？

1. # uname -a 查看當前核心的版本號碼

Linux localhost.localdomain 2.6.32-358.23.2.el6.i686 #1 SMP Wed Oct 16 17:21:31 UTC 2013 i686 i686 i386 GNU/Linux

2. # rpm -qa | grep kernel尋找要刪除的版本號碼

kernel-firmware-2.6.32-358.23.2.el6.noarch
abrt-addon-kerneloops-2.0.8-16.el6.centos.1.i686
kernel-devel-2.6.32-358.el6.i686
dracut-kernel-004-303.el6.noarch
kernel-2.6.32-358.23.2.el6.i686
kernel-devel-2.6.32-358.23.2.el6.i686
kernel-2.6.32-358.el6.i686
kernel-headers-2.6.32-358.23.2.el6.i686
libreport-plugin-kerneloops-2.0.9-15.el6.centos.1.i686
以上是我電腦上的核心版本號碼，其中紅色為要刪除的版本號碼

3. # yum remove kernel-devel-2.6.32-358.el6.i686
# yum remove kernel-2.6.32-358.el6.i686
4. 查看grub.conf發現多餘的啟動項已經刪除
