大佬教程收集整理的这篇文章主要介绍了将Debian fstab转换为通过linux-base使用UUID？，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

概述

我们有一些Debian 5系统仍在fstab中使用/ dev / hda.我们想将它们转换为使用UUID.这应该是通过“ linux-base”软件包(posTinst)自动完成的,但由于某些原因它并没有开始(可能有人已经运行它并且它保存了一些状态而不去做). 虽然通过手动编辑一堆文件可以切换到UUID,但以某种方式编写脚本会很有用. debconf和debconf-set-choices的各种咒

虽然通过手动编辑一堆文件可以切换到UUID,但以某种方式编写脚本会很有用. debconf和debconf-set-choices的各种咒语似乎都不起作用.

基本上,如何调用Debian提供的脚本来执行所有UUID转换？

解决方法

Per Gabor Vincze,来自 Ubuntu forums的脚本似乎做了一个不错的代码：

#!/bin/bash
# This script will change all entries of the form /dev/sd* in /etc/fstab to their appropriate UUID names
# you must have root privelages to run this script (use sudo)
if [ `id -u` -ne 0 ]; then                                              # checks to see if script is run as root
        echo "This script must be run as root" >&2                      # If it isn't,exit with error
        exit 1
fi

cp /etc/fstab /etc/fstab.BACkup
sed -n 's|^/dev/\([sh]d[a-z][0-9]\).*|\1|p' </etc/fstab >/tmp/devices   # Stores all /dev entries from fstab into a file
while read LINE; do                                                     # For each line in /tmp/devices
        UUID=`ls -l /dev/disk/by-uuid | grep "$LINE" | sed -n 's/^.* \([^ ]*\) -> .*$/\1/p'` # Sets the UUID name for that device
        sed -i "s|^/dev/${LINE}|UUID=${UUID}|" /etc/fstab               # Changes the entry in fstab to UUID form
done </tmp/devices
cat /etc/fstab                                                          # Outputs the new fstab file
printf "\n\nWrite changes to /etc/fstab? (y/n) "
read RESPONSE;
case "$RESPONSE" in
        [yY]|[yY][eE][sS])                                              # If answer is yes,keep the changes to /etc/fstab
                echo "WriTing changes to /etc/fstab..."
                ;;
        [nN]|[nN][oO]|"")                                               # If answer is no,or if the user just pressed Enter
                echo "AborTing: Not saving changes..."                  # don't save the new fstab file
                cp /etc/fstab.BACkup /etc/fstab
                rm /etc/fstab.BACkup
                ;;
        *)                                                              # If answer is anything else,exit and don't save changes
                echo "Invalid Response"                                 # to fstab
                echo "ExiTing"
                cp /etc/fstab.BACkup /etc/fstab
                rm /etc/fstab.BACkup
                exit 1
                ;;
esac
rm /tmp/devices
echo "DONE!"
