Linux
What We Cover.
Linux in production is not one distro. RHEL 5 through 10, SLES 11 through 15, Oracle Linux, Ubuntu LTS, and CentOS hosts that never got a migration budget.
We cover the kernel, userspace, and the cluster on top. Patches go on a change window you approve — not a Friday-night dump of every advisory.

FAQ
Questions about Linux.
Do you cover RHEL 5, 6, and CentOS 7?
Yes. EOSL Linux is common in production. Current RHEL, SLES, Oracle Linux, and Ubuntu LTS are in scope as well.
Is this a replacement for Red Hat or SUSE subscriptions?
This is independent OS support — engineers on the system. Subscriptions for packages and errata are a separate decision.
Can you mix Linux with AIX or Windows on one contract?
Yes. Coverage is scoped per host. Production Linux can be 24×7 while a lab stays on business hours.
