| ivebeenlinuxed | Hi All, I'm looking to do UEFI PXE netboot with Preseed - I have got the first bit to work (UEFI PXE), but not preseeding, anyone got any ideas? | 09:37 |
|---|---|---|
| cjwatson | Nothing special about UEFI for that; just put url= or whatever on the command line | 09:38 |
| ivebeenlinuxed | My understanding was UEFI couldn't boot pxeboot.0, so I opted for the grub-mkimage option (https://wiki.ubuntu.com/UEFI/PXE-netboot-install) where would I put the preseed "url="? | 09:39 |
| cjwatson | That particular method would require unpacking the .iso so that you can edit grub.cfg | 09:43 |
| cjwatson | I can't be responsible for everything on the wiki :-) | 09:43 |
| cjwatson | I would recommend using grub-mknetdir instead | 09:44 |
| cjwatson | Kernel command line arguments need to go on the relevant "linux" line in grub.cfg - you can poke around in the .iso to get an example | 09:45 |
| ivebeenlinuxed | The editing the ISO was going to be my next plan! I'll look up grub-mknetdir command now. Might have to make my debut edit on the Ubuntu Wiki! | 09:45 |
| cjwatson | There's also http://archive.ubuntu.com/ubuntu/dists/trusty/main/uefi/grub2-amd64/current/grubnetx64.efi.signed, which is the result of grub-mkimage signed for use with UEFI Secure Boot | 09:46 |
| cjwatson | You could then drop in a suitable grub.cfg | 09:46 |
| cjwatson | (The difference between grub-mkimage and grub-mknetdir is just that the latter produces something designed for shoving on a TFTP server - grub-mkimage isn't bad for this as such, it's just that that particular wiki page runs it in a way that embeds the netboot ISO) | 09:48 |
| ivebeenlinuxed | hmmmmm interesting plan! I will investigate now! | 09:49 |
| cjwatson | Looks like that wiki page would appreciate editing for how to do preseeding, indeed :-) | 09:50 |
| ivebeenlinuxed | Thanks for the help cjwatson - I have blogged the instructions here - I don't use dnsmasq, so I copied that bit from the old tutorial. Is it worth replacing the instructions with a set like this on the Wiki? (https://wiki.ubuntu.com/UEFI/PXE-netboot-install). Does anyone have any suggestions of things I should add/remove? | 11:31 |

| cjwatson | ivebeenlinuxed: Maybe talk with Kamal (orig author) and see what he thinks | 11:47 |
| Kingpatzer | hey folks: installed yesterday along side windows. Everything went great but windows wasn't in the grub menu. Followed some directions I saw online now nohting boots. looking at my drives, my / drive has only two files on it, @ and @home, which are direcotries. if I cd into '@' I see what looks like the / filesystem. Is that normal?? | 13:29 |
| directhex | afternoon. apparently http://ubuntuforums.org/showthread.php?t=2215103 is now a thing, it's started affecting me when moving my preseed file from 12.04 to 14.04. *something* is mounting /dev/vda1 (/boot) to /media, before partman tries to format stuff, and it's falling over as a result | 13:40 |
| directhex | it's mountmedia. | 16:37 |
| directhex | more specifically, it's preseed calling mountmedia which leaves things in an inconsistent state | 17:03 |
| directhex | "preseed_fetch file:///cdrom/preseed/custom.seed /tmp/debconf-seed" causes /media to be mounted & not unmounted | 18:33 |
| directhex | looks like a change joeyh made in debian-installer-utils (1.98) | 18:42 |
