Perhaps it means the OS doesn't need to be patched that frequently or
has a patch mechanism that avoids reboots? That's certainly worth
advertising (if only were true).
The top machine has been running for almost 6 years on FreeBSD 3.3 which
means the admin probably believes that "if it ain't broke, don't fix
it." I would also want to advertise the longevity of an OS.
(You might not like that last one if you're a hardware vendor :)
Also, a lot of work-arounds for security patches amount to "lock the
front door." So perhaps some systems don't need to be patched because
they're administered so as not to require immediate patching/upgrading.
I had trouble finding any relative numbers on the website. Individual
machines had an Availability % figure; but I couldn't find anything by
OS. Also, I didn't see any pivots that broke-down OSes by usage or
other crosstabs that would have been cool.
Headed for the second star to the right and straight on 'til morning...
