Hello,
tl;dr Question: Since I'm not using Ksplice and it doesn't even seem to be supported in my cloud instance, can I just turn this service off to get rid of this error? Do I need this? If I can just turn it off, do I just disable uptrack-prefetch.service, or something else?
I've just set up a free Oracle Cloud account and spun up an instance of Oracle Linux 8; I'm trying to figure out how to use it well enough to set up a Minecraft server, since a less technically inclined friend of mine wants to do the same thing and will be relying on me for tech support.
I've got a good bit of experience with Linux via Manjaro and Ubuntu on various SBCs, which I've used to run some overcomplicated docker container instances (I didn't know what I was doing at first, so I took the long way around), but I've never worked with Red Hat-type distros, so I'm going through a bit of a learning curve.
I just noticed I've got a non-functioning service, according to systemd. I don't recognize it, as it appears to be some unique-to-Oracle or -Red Hat thing, but it looks like I might not need it since I'm not using Ksplice? (I think? In my research so far it's described as a "legacy" mechanism for centralized kernel updates...)
