Priority:  major        |  Milestone:  undecided
 Version:  master       |   Keywords:  ansible
------------------------+-----------------------
 Pre 1.9, sudo/sudo_user was used to do privilege escalation.
 Post 1.9, become/become_user is the 'new' way.  While sudo/sudo_user
 can still be used,  it's deprecated.
