I would personally be leaning toward suppressing dhclient induced logging messages or at most logging them to ramdisk. Given the fact that the server also logs and the dhcp server is almost always a server within convenient reach, I don't think the syslog having dhclient messages from genesis is a big enough value given the cost.
From: "Daniel M. Weeks" <[email protected]> To: xCAT Users Mailing list <[email protected]> Date: 03/15/2013 01:24 PM Subject: [xcat-user] genesis: limit DHCP startup to connected interfaces This is a follow-up to my last patch for syslog, motivated mainly by the amount of log cruft present after resolving that issue. dhclient is started on all interfaces during /bin/doxcat whether those interfaces are connected or not. Since ethtool is present in the genesis image for x86 the attached patch uses it to check for a link and only starts dhclient on connected interfaces. If there is a good way to configure/determine if IPv6 is NOT used in the environment it would also be good to skip starting the v6 copies of dhclient when it is unnecessary. Before I go and add something unnecessary, is there currently a clean way to make this determination (perhaps guided by the site table)? Thanks. -- Daniel M.
