downloadohai-sysctl_less.tar.gz
Avoid gathering all data with sysctl which seems to hangsysctl_less
While it works fine for me @bdausses was seeing chef-client hang forever. It turns out running sysctl -a on his host was causing the system to hang. Besides this crash it actually takes about 2x longer to gather the additional data. This shaves a whole 0.033255 seconds from the total runtime.
