Indeed. At my place we reboot production machines every 90 days. Or
are meant to; I don't think management have worked out that rebooting
10,000 machines every 90 days means a lot of reboot activity!!
(The idea being to verify that services will come up after some form
of DC-wide outage; last think we want in a "business contingency" situation
is a few hundred servers not working properly 'cos the rc scripts are
broken)

Interesting..... This generally won't happen on a rock solid OS like
CentOS, unless someone really screwed up badly or it's a
super-custom build which can't be updated using normal CentOS
repositories.<br>
<br>
We don't reboot servers (CentOS at least), unless we really really
need to. For minor kernel updates that doesn't give much more than
what we need we don't reboot either. Only for more critical / major
/ highly important kernel updates, or hardware upgrades do we
reboot. <br>
