CentOS 7 restart fix #2

[chorankates]

• allowing restart() to be more flexible with exit codes

was catching a 256 exit code from the restart command, after 10-15 seconds. the reboot is/was initiated, but because we were expecting a 0, an uncaught exception was thrown

require sprintf('%s/../%s', File.dirname(File.expand_path(__FILE__)), 'path_helper')

require 'rouster'
require 'rouster/puppet'
require 'rouster/tests'

centos6 = Rouster.new(:name => 'centos6', :verbosity => 4, :sudo => true)
centos7 = Rouster.new(:name => 'centos7', :verbosity => 4, :sudo => true)

workers = [centos6, centos7]

workers.each do |w|
  p 'name[%]: ' % w.name
  p 'uptime:     %s' % w.run('uptime')
  p 'status: %s' % w.status()
  p 'rebooting...'
  w.restart(120)
  p 'status: %s' % w.status()
  p 'uptime: %s' % w.run('uptime')
end

exit

gives
