| ProfMac | I'm having fun with partman. I have found the log files at /var/log/partman during an unsuccessful installation, from one of the terminal windows. I am, as is everyone, debugging a preseed file. | 05:22 |
|---|---|---|
| ProfMac | I wonder if somehow I can feed the preseed file into the front of the pipe, and observer meaningful steps along the path. | 05:23 |
| cjwatson | ProfMac: Preseed files aren't imperative in a way that would cause that to make sense; they operate by setting a load of values in a database, which are used by later steps in the installer. | 09:35 |
| cjwatson | ProfMac: The usual swiss-army-knife for debugging is to pass DEBCONF_DEBUG=developer on the kernel command line when starting the installer. That will cause a trace of all debconf interaction (i.e. nearly everything) to be written to /var/log/syslog. | 09:36 |
| ProfMac | ah. I'll try that. I take it that it takes a while for people to grok the preseed partition descriptions. | 09:37 |
| ProfMac | I wish that the working examples worked :-) | 09:38 |
| xnox | CarlFK, but, we do support NVMe drives.... | 09:40 |
| xnox | CarlFK, e.g. we did SRU bug fixes for it - https://launchpad.net/ubuntu/+source/grub-installer/1.128ubuntu5.1 | 09:42 |
| cjwatson | ProfMac: Declarative partitioning is certainly the most complicated part of the task by a long shot. | 09:52 |
| ProfMac | I would like to find documentation on how partman works, and a working example with LVM and/or raid. I have several apparantly well written examples, but they don't work in my hands. | 09:54 |
| ProfMac | is there a tool that reads an existing set of disks, and produces a preseed file that implies how to re-create them? | 09:57 |
| cjwatson | I don't believe so, unfortunately. | 10:00 |

| CarlFK | xnox: thanks | 12:08 |
| ProfMac | I notice the X-window system is alive during install. I have used ssh to reach out to another system. openssh-server is not installed, however. Is there any way to reach in from the outside during the install process? | 20:21 |
| CarlFK | ProfMac: well.. here is what I came up with like 6 years ago: | 20:46 |
| CarlFK | https://github.com/CarlFK/veyepar/blob/master/setup/nodes/pxe/shaz/var/www/ec/early_command.sh | 20:46 |
| CarlFK | d-i preseed/early_command string cd /tmp && wget http://$url/ec/early_command.sh && chmod u+x early_command.sh && ./early_command.sh | 20:47 |
| ProfMac | CarlFK, it looks nice and clean. | 20:49 |
| CarlFK | d-i preseed/late_command string /tmp/misc/isshd.sh | 20:50 |
| CarlFK | from what I remember, i can't run isshd.sh at the time early_command runs - it errors and all goes bad | 20:51 |
| CarlFK | so I grab all the files, let them sit till needed. like if the installer stops at some point, I can hit a-f2, /tmp/misc/issd.sh and then ssh in from my laptop | 20:52 |
| ProfMac | Yes, that is pretty much the plan, ssh in when it needs attention. | 20:53 |
| CarlFK | I just found "preseed/run” but haven't tried it. nor can I find any docs. there was a bug report that said it ran pretty early. there is prof it exits here: https://help.ubuntu.com/lts/installation-guide/armhf/apbs02.html | 21:03 |
| CarlFK | I am always a little bothered that I need to go to the keyboard of the machine being installed | 21:04 |
| CarlFK | I think there is something to provide the anyway, but never figured out how to make that work either | 21:05 |
| CarlFK | xnox: does the 128 in grub-installer/1.128ubuntu5.1 mean I don't have it in BusyBox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built-in shell (ash) | 23:09 |
