worth noting  the security model in jenkins is such that it is not really safe to mix trusted and untrusted slaves  and it is also not generally safe to reuse untrusted slaves  as such we keep our trusted reusable slaves bound to a separate jenkins master from our nodepool managed slaves  if you have a similar split  you can simply avoid running this for the jenkins masters handling your reusable slaves and only use it for jenkins masters handling your nodepool managed slaves
