It really wasn't, you know. I predate GRUB too and when I started
playing around with Linux, LILO was rather new and experimental and I
used the `loadlin` command.

It really wasn't. I mean, you might have used it a lot -- I am not
saying this never ever happened -- but I've been working with Linux
for 26 years now and I was running it in production in the 20th
century. This was _never_ standard practice of _anyone_  I have ever
talked to or worked with. I have, TTBOMR, *never* seen such a
deployment.

You amaze me.

As you wish. I am not saying it doesn't work; I am saying it is
complicated and I prefer to avoid it.

When I deployed Linux boxes in production, if they contained anything
important they had hardware RAID controllers. (My first ever one was
an internal installation-medium server and all it held was CD images,
so it wasn't important and was easily rebuilt.)

More recently, they'd run on top of VMs and the storage was all
virtualised anyway, so I don't need in-VM virtualisation as well.
