[^1]: Typically for unmanaged services (e.g. the GE2/1 detector safety system)
or development purposes. While the machine is managed via Puppet, tools and
libraries are manually installed whenever needed (`gcc`, `java`, `git`,...)
Do not rely on system persistence! The GEM Dropbox is also disabled on that
specific machine, so that no GEM RPM packages are available and
automatically installed.
