問題文
An administrator at a logistics company needs to reach a shell on a server whose root filesystem mounts but whose network stack and most services must stay down during the repair. Which startup target fits this requirement?
選択肢
- The rescue target, which brings up the root filesystem and a single administrative shell without starting the normal multi-user services.
- The graphical target, because the graphical layer runs independently of the network and therefore isolates the repair from the running services.
- The emergency target, which is the correct choice whenever the root filesystem mounts successfully, since it starts the same set of services as rescue but additionally leaves the network available for remote administration.
- The multi-user target, since it is the default on servers and therefore the safest place to perform repairs.
