[04:40] <ProfMac> I have a seed file that installs with lvm partitions on 14.04.3.  It is not totally clean, but it is at the point that I can match the results and /var/log/syslog, and make forward progress in modifying my preseed file.  Yeah!
[04:41] <ProfMac> The biggest step forward was to quit trying to get 12.04.5 to respond meaningfully :-)
[04:50] <CarlFK> ProfMac: hey there
[04:53] <ProfMac> CarlFK, hey there
[04:53] <CarlFK> maybe you can help. I am installing to an ssd that shows up as Apr 21 04:21:05 frontend: --> SET partman-auto/disk /dev/nvme0n1
[04:53] <CarlFK> but I am getting  "no root filesystem defined"
[04:53] <ProfMac> oh lord.  I have known about preseeding for almost a week now...
[04:54] <CarlFK> well, you are doing disky things.  I just try to go with the default
[04:55] <ProfMac> Yep, I see that error a lot.  Do you know about running an xterm during the install, and running gedit /var/log/syslog to see what is happening while the install is still alive?
[04:57] <CarlFK> kinda  - all my installs use the text based installer.  so no x anything.. and I have a script that scp's all the logs and stuff to another box so I can use vim and whatever tools
[04:57] <ProfMac> Are you running the standard vanilla install from the distribution disk, or are you doing more customization.
[04:57] <CarlFK> oh, and cut/paste lines int irc. like up there
[04:58] <ProfMac> ah.  You are more advanced than I am there.  I can't throw an xterm to another machine yet.
[04:58] <CarlFK> http://archive.ubuntu.com/ubuntu/dists/zesty/main/installer-amd64/current/images/netboot/netboot.tar.gz
[04:59] <CarlFK> put that on what we will call the pxe server
[04:59] <CarlFK> target machie, bios set to pxe boot that
[04:59] <ProfMac> My most recent misadventure with no root filesystem was when I somehow specified a lvm group, but never attached one of them to a physical disk.
[05:00] <ProfMac> cool.
[05:00] <CarlFK> then the kernel append, preseed.cfg and those scripts all live on the server
[05:00] <CarlFK> I can edit, save, reboot the target, ... don't have to move usb sticks around
[05:00] <ProfMac> got it.  sounds clever, and real work related.
[05:05] <ProfMac> This is all too new for me to offer good advice, but the old approach of only change 1 thing, keep good logs, append unixtime to filenames, sort of at random led me to my first success, occurring as we speak.
[05:06] <CarlFK> yay!
[06:00] <CarlFK> welp.. tried to install zesty... grub-installer didn't error, but bios says "insert boot device and hit any key"
[06:02] <CarlFK> bed time now.  will poke again tomorrow.
[06:14] <ProfMac> good luck.
