Booted straight to the CentOS 4 ISO, went into linux rescue, updated the initrd img and bam. working system from the current (as of 4 days ago) manual disk images I made.

Next project to re-learn how they restore data files. Have not done that in almost 10 years. Having no virtual infrastructure to play with, prior to this, made that harder.

We use ghost adapters to allow EDID hi res with no head attached, I wonder if there is one that forces 640x480? I'll search around...

@DustinB3403 You never touch grub yourself. You let the system take care of it for you when it adds or removes kernels.

As to removing old kernels, it depends on the distribution you use. A good distro just takes care of this for you. The annoying ones make you do it manually.

RedHat/CentOS/Fedora = automatically cleans up older kernels. You don't do anything and it will keep a sane number by default. I think it's 4 and a recovery option.

Debian/Ubuntu = keeps all kernels till you manually remove them. I forget offhand what the command is besides it's an option for apt.

This is one reason I'm happily moving things from the old rental box to my new server for my home lab. The old rental box has Ubuntu with a tiny little 256MB /boot partition. It can keep ~3 kernels, and that's it, ugh!

You can install without /boot. IIRC there is a other config change with unattended-upgrades to auto remove kernels.

You normally can, yes. Since my current home lab box is a rental, I could only choose from the options they gave me at the time. Today, they'd let you use your own iso, but still wouldn't recommend them for anything other than a test lab.

@scottalanmiller Ubuntu is a surprising choice for you 😉

Runs ScreenConnect.

So does Fedora.

Always fail when I do it, there is some trick to it. Happen to know what's needed so that it doesn't just put hashes on the screen for forever?

Yes. Grubs editor is inside Linux.
