New Revision: 196623
URL: http://svn.freebsd.org/changeset/base/196623

Log:
  MFC r196505:
  
    When "jail -c vnet" request fails, the current code actually creates and
    leaves behind an orphaned vnet.  This change ensures that such vnets get
    released.
  
    This change affects only options VIMAGE builds.
