# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda2
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux Server (2.6.18-92.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-92.el5 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.18-92.el5.img
想在kernel /vmlinuz-2.6.18-92.el5 ro root=LABEL=/ rhgb quiet 这一行末尾追加一句话：selinux=0
怎么实现？？？

写掉了个符号
应该是
sed -i "/kernel /vmlinuz-[0-9]/s/$/ selinux=0/g" grub.conf
