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!"
