Deepin挂载内存盘

最近检查了一下硬盘，发现双系统的Deepin分区损害严重。笔者猜想是由于其分区太小，经常擦写的缘故吧。故此，设置内存盘。

一、修改/etc/fstab

tmpfs　　/var/cache/apt/archives　　tmpfs　　size=1G,mode=0777     0 0

或者

none　　/var/cache/apt/archives　　tmpfs    rw,noexec,nosuid,nodev,size=3G,mode=0777 0 0

# 注意大小一定要整数而且要少于可用内存，如果不整数可以用M为单位。否则会导致机器无法启动。若需要内存为动态分配，设置挂载文件系统为none。

二、修改/etc/init.d/rcS

chown zhouyixing:zhouyixing /var/cache/apt/archives

三、设置浏览器缓存目录

mkdir -p /var/cache/apt/archives/chrome
mkdir -p /var/cache/apt/archives/firefox
if [ -d /var/cache/apt/archives/firefox ] ; then
    if [ ! -e /home/zhouyixing/.cache/mozilla ] ; then
        ln -s /var/cache/apt/archives/firefox/ /home/zhouyixing/.cache/mozilla
    fi
fi

if [ -d /var/cache/apt/archives/chrome ] ; then
    if [ ! -e /home/zhouyixing/.cache/google-chrome ] ; then
        ln -s /var/cache/apt/archives/chrome/ /home/zhouyixing/.cache/google-chrome
    fi
fi

四、附加文件

    #!/bin/bash  
     
    VAR_ACTION= 
    VAR_CMD= 
    VAR_DEST_PATH= 
    VAR_SRC_PATH= 
     
    function echo_red() 
    {  
        echo -e "\033[31;40m" "$@" "\033[0m" 
    } 
     
    function echo_green() 
    {  
        echo -e "\033[32;40m" "$@" "\033[0m" 
    } 
     
    function echo_yellow() 
    {  
        echo -e "\033[33;40m" "$@" "\033[0m" 
    } 
     
    function echo_error() 
    { 
        echo_red $@ 
    } 
     
    while getopts ":a:c:d:s:" options   
    do   
        case ${options} in   
        a) 
            echo_green "VAR_ACTION = $OPTARG"   
            VAR_ACTION=$OPTARG 
            ;;   
        c) 
            echo_green "VAR_CMD = $OPTARG"   
            VAR_CMD=$OPTARG 
            ;;   
        d) 
            echo_green "VAR_DEST_PATH = $OPTARG"   
            VAR_DEST_PATH=$OPTARG 
            ;; 
        s) 
            echo_green "VAR_SRC_PATH = $OPTARG"   
            VAR_SRC_PATH=$OPTARG 
            ;; 
        \?) 
            ;; 
        esac 
    done 
     
    case ${VAR_ACTION} in 
    build) 
        eval ${VAR_CMD} 
        ;; 
    copy) 
        if [ "${VAR_DEST_PATH} " = " " ] ; then 
            echo_error "destination is empty" 
        elif [ "${VAR_DEST_PATH} " = " " ] ; then 
            echo_error "source path is empty" 
        elif [ ! -d $VAR_SRC_PATH ] ; then 
            echo_error "source directory is not exist!" 
        else 
            if [ ! -d $VAR_DEST_PATH ] ; then 
                mkdir -p $VAR_DEST_PATH 
            fi 
     
            cp -rf $VAR_SRC_PATH/* $VAR_DEST_PATH 
        fi 
        ;; 
    patch) 
        if [ -d ./tmp ] ; then 
            echo_yellow "delete the folder ./tmp" 
            rm -rf ./tmp 
        fi 
        mkdir ./tmp 
        echo "#!/bin/bash" > ./var.sh                                                        &&  \ 
        git diff --stat                                                                     |   \ 
        grep \|                                                                             |   \ 
        awk '{for(i=3;i<NF;i++) {printf "cp --parents " $1 " ./tmp/\n"}}' >> var.sh            &&  \ 
        echo "exit 0" >> var.sh                                                               &&  \ 
        chmod a+x ./var.sh                                                                  &&  \ 
        /bin/bash ./var.sh                                                                  &&  \ 
        rm ./var.sh 
     
        if [ "${VAR_DEST_PATH}" != "" ] ; then 
            echo_green "move to "${VAR_DEST_PATH}" ..." 
            if [ ! -d ${VAR_DEST_PATH} ] ; then 
                echo_yellow "create path ${VAR_DEST_PATH}" 
                mkdir -p ${VAR_DEST_PATH} 
            fi 
            cd ./tmp/ 
            cp -rf * ${VAR_DEST_PATH} 
            cd .. 
            rm -rf ./tmp/ 
            echo_green "done" 
        fi 
        ;; 
    \?) 
        echo_error 
        ;; 
    esac
