問題文
A team wants to shorten the software installation on many hosts by unpacking the delivered image straight into the target directory. Which statement describes what that style of installation changes?
選択肢
- The directory into which the image is unpacked has to be empty of any earlier release, so the configuration script then upgrades the release that the host was running before the image was unpacked into it.
- The directory into which the image is unpacked is chosen by the image itself, so the configuration script then reports the path that was used and the operators record it for the next host.
- The directory into which the image is unpacked becomes the home itself, so the configuration script is then run from inside that directory instead of from a separate staging area that the installer created earlier.
- The directory into which the image is unpacked becomes a staging area, so the configuration script then copies the files into the real home and removes the staging area when the copy has finished.
