+
+Via `shared_fs_path` the path to a directory on a shared filesystem (NFS, etc.) can be provided,
+which can be leveraged by the `bot/build.sh` script to store files that should be available across build jobs
+(software source tarballs, for example).

+If build logs should be copied to a particular (shared) directory under certain conditions,
+for example when a build failed, the `build_logs_dir` can be set to the path to which logs
+should be copied by the `bot/build.sh` script.
