Greetings,

Thanks for the wonderful replies on this post.

Actually, this is an experiment in minimalism.

Sorry for not being clear on this footprint idea.  Actually, I am looking
at the minimal disk (boot CD) footprint and was playing with the idea of a
type of "ram-based live-cd" with FS mount mapping in the drives for VM
storage, and a few other essential directories like home, root, etc..
mostly persistent data directories.  The idea was to have the absolute
smallest proxmox cd/usb boot footprint and have the drives for user/VM data.

This might be interesting as I actually never hear of the i3 wm before but
it looks a lot like the "terminator" console which I installed on Ubuntu
16.04 that has similar functionality.

For this sub-project, and although some in the community may not see a need
for which I do have a very specific use case in mind and potential follow
on growth model.

I just what to have proxmox running and then have a very simple X-Server to
service just one application (NoMachine NX client or X2GO client perhaps)
that comes up on boot. Ideally, it would be good if I could somehow run the
X-Server in a VM perhaps and pass-through to the video so as not to add
more components to the hypervisor base, but if that is not possible then
adding the X-Server and remote client to be base could work for now.

I have actually set up the base Proxmox VE on 4 LAN systems and 2 VPS
systems that I was initially playing around with to see if I could cluster
LAN nodes across the WAN to the VPS nodes just to see if it could be done
easily but further wanted to set up a self-balancing VPN like Tinc, or
MeshBird to do it. Never got it all to work together smoothly so now I am
looking at another direction for a second project to test and will come
back to the clustering sub-project stuff a bit later once this part is
working as it is also related to the first one in just being another part
of the same master project. Both projects will come together at some point.


Thanks again and have a great day,
Lonnie
