Warn the user about the usage of output/target as the root filesystem
A very common mistake done by our users is that they use output/target/ directory as their root filesystem. Even though this is loudly documented in our Buildroot manual, people don't read documentation, so it is not sufficient. This patch adds a text file named output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why output/target isn't appropriate to use as the root filesystem. The process is: * At the beginning of the build, right after the skeleton has been copied, support/misc/target-dir-warning.txt is copied to output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM * In the filesystem images creation code, this file is removed before launching fakeroot, and restored right after that, so that this file is not present in the generated root filesystem images. Note that the file has not been added to the default skeleton for two reasons: * It would have annoying to have in our source tree a file named in capital letters inside system/skeleton/ * The proposed way works even if the user uses a custom skeleton.
