载入系统变量/etc/sysconfig/network

if [ -f /etc/sysconfig/network ]; then     . /etc/sysconfig/network fi

如果HOSTNAME不存在，则定义为localhost if [ -z "$HOSTNAME" -o "$HOSTNAME" = "(none)" ]; then     HOSTNAME=localhost fi

如果不存在/proc/mounts则挂载proc和sysfs

if [ ! -e /proc/mounts ]; then     mount -n -t proc /proc /proc     mount -n -t sysfs /sys /sys >/dev/null 2>&1 fi

如果下目录不存在则加载usbcore模块，并挂载。-n可以在/etc/mttab只读的情况下挂载 if [ ! -d /proc/bus/usb ]; then     modprobe usbcore >/dev/null 2>&1 && mount -n -t usbfs /proc/bus/usb /proc/bus/usb else     mount -n -t usbfs /proc/bus/usb /proc/bus/usb fi  载入系统环境变量 . /etc/init.d/functions

# Check SELinux status selinuxfs="$(fstab_decode_str `LC_ALL=C awk '/ selinuxfs / { print $2 }' /proc/mounts`)"

确定SELINUX_STATE状态，如果不存在则设置为SELINUX_STATE=1 SELINUX_STATE= if [ -n "$selinuxfs" ] && [ "`cat /proc/self/attr/current`" != "kernel" ]; then     if [ -r "$selinuxfs/enforce" ] ; then         SELINUX_STATE=`cat "$selinuxfs/enforce"`     else         # assume enforcing if you can't read it         SELINUX_STATE=1     fi fi

如果SELINUX_STATE变量值存在并且restorecon存在并且有执行权限，重新对/dev打标

if [ -n "$SELINUX_STATE" -a -x /sbin/restorecon ] && LC_ALL=C fgrep -q " /dev " /proc/mounts ; then     /sbin/restorecon  -R /dev 2>/dev/null fi
