      In order to install some internal tools within /opt/tools through a Jenkins job, I have created a /opt/tools directory belonging to jenkins:jenkins and where user jenkins only (the user running the slave) has rwx rights.
      Trying something like :

      stages {
        steps('xyz') {
          dir('/opt/tools') {
             sh "pwd"

      Fails with an exception ending with :

      It appears that Jenkins tries to create a tools@tmp directory at the same level as tools. Yet, there is absolutely no reason for the tools root directory to be writable for any user.
      And as far as /opt is concerned here, for sure it must not be writable for anybody else than root.

      Additionnally, such @tmp directory is not removed once the build is achieved. Even though it seems that the directory is empty, I think that Jenkins should remove it to give back a clean environment.
