  28 # traditional System V treatment of /var/tmp, invoke the following
  29 # commands.:
  30 #
  31 # # svccfg
  32 # svc:> select system/rmtmpfiles
  33 # svc:/system/rmtmpfiles> setprop options/clean_vartmp="true"
  34 # svc:/system/rmtmpfiles> select default
  35 # svc:/system/rmtmpfiles:default> refresh

  42 # across boots. The following adopts the traditional System V behavior
  43 # of removing everything in /tmp, unless /tmp or any of its subdirectories
  44 # are mount points for another filesystem.
