我们有一些在fstab中仍然使用/ dev / hda的Debian 5系统。 我们想转换他们使用UUID。 这应该是通过“linux-base”包（postinst）自动完成的，但由于某种原因，它不能踢（也许有人已经跑了它，并保存在某个地方的某个地方不这样做）。
虽然通过手动编辑一些文件来切换到UUID当然是可能的，但是以某种方式编写脚本会很有用。 debconf和debconf-set-selections的各种咒语似乎不起作用。
所以基本上，如何调用Debian提供的脚本来执行所有的UUID转换？
Per Gabor Vincze从Ubuntu论坛的脚本似乎做了一个体面的代码：
#!/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/\([sh]d[az][0-9]\).*|\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!" 该脚本将在/var/lib/dpkg/info/linux-base.postinst中。 您可以手动启动它，或者在调用dpkg-reconfigure之前查找可以清除的“已迁移”标志。
