lef*_*out 5 linux grub boot ubuntu tmp
假设我正在运行一些冗长的过程，包括两个步骤：a生成一个大的中间文件，例如/tmp/aoutput，然后b读取该文件并对其执行进一步的操作。
现在系统在执行该b步骤时崩溃了。是否可以以一种不会像启动时通常发生的那样删除 的内容的方式重新启动系统/tmp，以便我们可以立即重新启动b而无需先a完全运行？
这当然假设/tmp没有安装在tmpfs.
我想排除涉及物理取出 HDD/SSD 或使用实时 USB 介质启动的解决方案。在我现在的具体情况中，它实际上是一个具有全盘加密的 SSD，但我也对仅适用于非加密驱动器的解决方案感兴趣。
编辑现在仍然保留这个问题，因为这两个答案都没有提供一个无需实时媒体或事先调整配置即可工作的解决方案。也许确实不可能有其他方式，但看起来很奇怪：GRUB 不是已经挂载分区来引导 Linux 了吗？如果是这样，是否有办法在启动之前手动移动文件systemd？也许我错了，我对引导加载程序知之甚少；但我想听听为什么这是不可能的。

是的。
\n有两种情况可能会导致文件丢失/tmp：
tmpfs：许多现代系统都会安装临时文件系统（例如 RAM 磁盘），这/tmp意味着内容在关闭时总是会丢失。
清理/tmp. 这是一个可配置的脚本，用于清理/tmp.
请检查命令的输出df /tmp。在情况 1 中，它看起来类似于：
$ df /tmp/\nFilesystem 1K-blocks Used Available Use% Mounted on\ntmpfs 12290040 276 12289764 1% /tmp\n（重要的是第一栏。. tmpfs）
/etc/tmpfiles.d在情况 2（您的情况）中，您通常可以通过查看-- 请参阅中的文件来了解更多信息man tmpfiles.d。请添加输出
grep -s . /*/tmpfiles.d/*.conf /*/*/tmpfiles.d/*.conf\n对于你的问题。\xe2\x9f\xb9 您的文件是/usr/lib/tmpfiles.d/tmp.conf您需要编辑的文件，例如sudo nano /usr/lib/tmpfiles.d/tmp.conf根据以下示例应用更改。
这是一个示例文件/etc/tmpfiles.d/tmp.conf：
# see tmpfiles.d(5)\n# always enable /tmp folder cleaning\nD! /tmp 1777 root root 0\n\n# remove files in /var/tmp older than 10 days\nD /var/tmp 1777 root root 10d\n第一个条目D! /tmp 1777 root root 0意味着该/tmp文件夹将在每次启动时被删除并重新创建。您可以注释掉该行，并可能添加类似于该文件中下一个非注释行的行：
# see tmpfiles.d(5)\n\n# # always enable /tmp folder cleaning\n# D! /tmp 1777 root root 0\n\n# Keep files in /tmp but not very old ones\nD! /var/tmp 1777 root root 30d\n\n# remove files in /var/tmp older than 10 days\nD /var/tmp 1777 root root 10d\n由于系统现在尚未启动，您需要从 Live DVD/USB 介质启动，然后挂载您的系统分区，例如挂载到/mnt. /mnt/usr/lib/tmpfiles.d/tmp.conf然后按照上述方法编辑该文件。
