The blurred out text is the name of one of the computers on my AD domain - of which this new Fedora box knows (or at least should know) nothing about.
I bet you'll find it's in a DNS record somewhere, too.
Of course - the new IP it has on the new subnet it's part of.

As for reverse DNS still having an entry - it hadn't been scavenged yet, that's set for 30 days, and the fact that it pulled this name in didn't hurt anything, it was simply odd.
How do you define that as odd? Isn't this the least odd possible thing?
I see your point - but what are the chances that you're going to have reverse DNS setup before setting up the server?
In a business where they are planning their deployments and managing IT: extremely high.
It's just the logical way to do it. Having haphazard records doesn't make logical sense. That's just sloppy. Basic infrastructure planning - using the tools you have as they are designed.

@Dashrender said in Fedora install weirdness:
I know I've NEVER done it on purpose. The only worked because DHCP gave an IP to my server that happened to coincide with an existing reverse DNS entry, which only existed because it hadn't been scavenged yet, so the situation seems odd to me.
Basically you have two issues. One, you aren't managing your system and just letting it exist. And two, you have the system not in place intentionally but using it as just part of an infrastructure that you didn't tie this system too. Had you put this system under AD to match the infrastructure you had chosen, it would have done exactly what it was supposed to do.
You are falling into a weird space of running infrastructure haphazardly, and trying to run two different systems that share some infrastructure and not others, and seeing the management of the one messing with the other because you are keeping them blind to each other.

Well then, where is the confusing part?

I always set the host name and IP so I have not never run into this issue personally.
Setting the hostname, of course. but setting the IP? Never. DHCP reservation, unless a hypervisor, router, or DHCP/AD/type server.
In regards to the amount of work, isn't Static IP basically the same as a DHCP reservation?
Up front, yes. Long term, generally no.
Not just generally no. Definitely no. Example, I moved a client from a /24 to a /23. Because it was almost all reservations, only like 4 systems had to have their network settings updated.
The rest was just a reboot.

OK we've beat the hostname issue to death.
What about the storage name? Where did that get it's name from?

I thought that we had moved onto that a bit ago.

It always creates that using the hostname that was assigned at install time. I always set that, and don't have reverse lookup records, so I don't see that happen. Makes total sense that it would tho.

OK - well, then this makes no sense what so ever - as I mentioned, I set no hostname, so fine, it pulled one form reverse DNS, but as you can see in my examples at the top.. the two DO NOT MATCH. What's in the hostname is totally different from whats in the storage name.
vs
The names don't match up at all. But the storage name is a the same as a computer on my network, is in DNS, but not on that IP in DNS, nor reverse DNS.

Ah, I missed that. Yeah, that is odd.

If you left the default hostname (localhost.localdomain) alone, the default storage name will be fedora-root and fedora-home.

I would have thought so too - but you can clearly see that's not the case.

updated my post above yours with the screen shots.

OK after an offline conversation with JB - Scott's saying we were already talking about my storage name issue makes sense.
It's likely that setup grabbed IP Address A from DHCP, which happened to coincide with an old record from my boss's laptop in Reverse DNS. Fedora installer looked that name up, used it to make the storage name.
Then after install, Fedora used the newer ID to get a DHCP address, my DHCP server saw it as a new device and gave it a different IP. and the rest is history.
Thanks everyone for helping me understand what happened.
-
Ah, if DHCP was giving different IP addresses. that makes sense.

It has to. Because the installer uses the MAC address. But Fedora uses the Machine ID for DHCP identification.
