Communities, Enterprises and All the Rest
summary
Enterprises treat change as cost, not a feature: maintenance windows can be as small as 15 minutes a year, critical workloads run 6–10 months, and customers ask for 13 year support cycles. Backporting creates a Frankenstein kernel with thousands of patches so vendors now prefer a rebased kernel strategy and careful QA. Long‑running systems force investment in kernel live‑patching; SUSE Labs launches Kraft in SLES 12 to replace kernel functions without rebooting. Systemd replacement in SLES 12 ships with surprisingly positive beta feedback.
