On: Stratus: Servers that won’t quit – The 24 year run...

I love the idea of that, but it also means no security patches for that same period of time. I'd be weary of placing that host in any network with publicly-routable hosts.

No security patches to the kernel. You can certainly upgrade user-space items (daemons and the like...)

I heard you could hot patch the kernel as well somehow.

[PeCaN → delinka]

You can use stuff like https://github.com/dynup/kpatch or http://www.ksplice.com/ to apply security patches to a running Linux kernel, but that's still pretty new stuff.

Stratus has been doing that since the 90s, though :-)
