svn commit: r252797 - head/usr.sbin/sysrc

[Devin Teske]

Author: dteske

New Revision: 252797
URL: http://svnweb.freebsd.org/changeset/base/252797

Log:
  Do not inherit $SYSRC_VERBOSE from operating environment. The concern is
  that when a user (such as myself) which has SYSRC_VERBOSE=1 in his/her
  ~/.bash_profile or such that when they are told to execute a command like:
  
  	hostname `sysrc -n hostname`
  
  NOTE: To activate a recently configured hostname.
  
  If $SYSRC_VERBOSE is set, then POLA is violated because the output of sysrc
  is indirectly influenced (making for an inconsistent experience).
