[16:59] <mgedmin> the hostname of my VPS switched from what I set it to (via hostnamectl and vi /etc/hosts) back to vps123456 during the upgrade from 18.04 to 20.04
[16:59] <mgedmin> I'm pretty sure cloud-init did it
[17:00] <mgedmin> what's the right way to undo this?
[17:00] <mgedmin> I've never used cloud-init before (at least not knowingly)
[17:00] <mgedmin> AFAIU I ought to create a /etc/cloud/cloud.cfg.d/99_local.cfg with hostname: myhostname.example.com
[17:00] <mgedmin> and then run something?  service cloud-init restart?
[17:02] <mgedmin> seems to've worked
[17:02] <mgedmin> but wow /etc/hosts is a mess
[23:16] <jayjo_> The ubuntu server docs seem to indicate that autoinstall in 20.04 LTS is for VM installations (https://ubuntu.com/server/docs/install/autoinstall-quickstart). Is there a way to automate an installation from a USB drive?
[23:32] <jayjo_> Should I prefer the debian 'preseed' methods? I use ubuntu in public clouds, I've never tried to automate installation on my own machines
[23:34] <sarnold> jayjo_: the preseedable images won't be available for future releases
[23:35] <sarnold> (and even though they were built for 20.04, I don't think they received any testing at all; they were a side effect of the build process and were released as an untested 'hopefully helpful' kind of thing, I think)
[23:37] <sarnold> jayjo_: don't think anything on that autoinstall quickstart guide is too specific to VMs -- just that kvm line. You can add the same 'autoinstall ds=nocloud-net;s=http://something/' line to the kernel command line during the normal server bootup, no?
[23:57] <jayjo_> the quickstart guide sets up a python server on a LAN machine that can serve the cloud-init data. Can that configuration be on the USB drive, either on another partition, or can I modify the bootable part of the drive?
[23:57] <jayjo_> Do you mean adding via https://wiki.ubuntu.com/Kernel/KernelBootParameters?
