The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked. I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.
