svn commit: r194257 - head/sbin/init

[Ed Schouten]

Author: ed

New Revision: 194257
URL: http://svn.freebsd.org/changeset/base/194257

Log:
  Remove redundant code from runshutdown() now tcsetsid(3) works reliably.
  
  We can now just call setctty() without any problems. This means the
  shell running the shutdown script is now the session leader, just like
  on startup.
