--- Begin Message ---Greetings, I'm looking at FAI, and I think I can almost figure out how to do what I want, but I thought I'd ask for some advice here since I haven't been able to find the last few bits in the docs or examples. I'm trying to do a new install of any sane linux to a remote machine where I don't have physical access. My target machine is starting as an unusual and disturbingly old build (an ubuntu 14.04 with a custom kernel) that's missing many of the normal basics you'd expect to be there, and for complicated reasons I can't fix, an ordinary do-release-upgrade path does not work (there are a number of key packages suppressed by some kind of jail the root user is in). However, I do have curl, grub 2.02, ssh access with root, and the power to mount things, plus disk space I can blow away. So I'm thinking I can get to where I want to be by installing from an FAI iso image and using a manual grub menuentry for the iso like they describe in https://help.ubuntu.com/community/Grub2/ISOBoot But it looks like the FAI docs really want me to use dhcp, and I cannot do this thing. I don't have control of the environment there where the machine is located. If that's truly a requirement for FAI, I'll have to find another way. But I'm hopeful I can get this to work, because FAI seems to have *almost* everything I need, and is a lot closer than, say, an ubuntu server iso as a starting point for a remote install where I won't be able to use a console or keyboard. I found an old mailing list post that said this worked once for someone: https://lists.uni-koeln.de/pipermail/linux-fai/2014-July/010657.html I'm trying to figure out how to make something similar work for me now, though I'd rather use a local iso mount than nfs for this. I found a few things in the FAI iso that look like they can do what I want, but I'm not sure how to make them happen. Specifically, I pulled down a Debian 10 (buster) FAI image, mounted it, mounted the LiveOS/squashfs.img inside that, and then mounted the LiveOS/ext3fs.img inside that. Inside that at the var/lib/fai/config/scripts/DEBIAN/30-interface file, I see some promising support for METHOD=static, both in netplan_yaml and in iface_stanza. (I could not find this file in the fai github repo, but if you want to see the code I'm talking about, it was pasted in an earlier message here: https://lists.uni-koeln.de/pipermail/linux-fai/2018-May/012019.html ) What I'm confused about at this point is how to set the variables those things depend on, such as METHOD=static, and IPADDR, NETMASK, GATEWAYS, and BROADCAST as my target's current values, in the way that makes them get picked up during the installation. I get the impression it's possible to do this from the grub menuentry, but I haven't figured out how yet (Perhaps export? But I'm not sure, this seems a different use than the examples the grub docs give.) I'm going to start doing some trial and error on this in the morning with some local machines that I do have physical access to, and that I can bring back to the same state as my target machine after I break them. But if there's anyone out there who knows the magic syntax I should use, or who can make a good suggestion of things to try, I would be very grateful. I'm not very familiar with grub, so I'm expecting this will be a long and painful trial and error process unless someone comes to the rescue with a good suggestion. So I thought I'd send out this plea before I begin. Wish me luck, and please send advice if you're able. I'll try to post again if I find something that works. Cheers, Jake
