rc.local配置
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
# Miscellaneous fixes for Xen VPS.
pkill -f nash
depmod
modprobe blktap
modprobe tun
modprobe fuse
mkdir -p /dev/net
mknod /dev/net/tun c 10 200

rm -rf /lib/tls; rm -rf /usr/lib/tls
echo hwcap 0 nosegneg > /etc/ld.so.conf.d/kernelcap-`uname -r`.conf
