[09:37] <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?
[09:38] <cjwatson> Nothing special about UEFI for that; just put url= or whatever on the command line
[09:39] <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="?
[09:43] <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 :-)
[09:44] <cjwatson> I would recommend using grub-mknetdir instead
[09:45] <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!
[09:46] <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
[09:48] <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)
[09:49] <ivebeenlinuxed> hmmmmm interesting plan! I will investigate now!
[09:50] <cjwatson> Looks like that wiki page would appreciate editing for how to do preseeding, indeed :-)
[11:31] <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?

[11:47] <cjwatson> ivebeenlinuxed: Maybe talk with Kamal (orig author) and see what he thinks
[13:29] <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??
[13:40] <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
[16:37] <directhex> it's mountmedia.
[17:03] <directhex> more specifically, it's preseed calling mountmedia which leaves things in an inconsistent state
[18:33] <directhex> "preseed_fetch file:///cdrom/preseed/custom.seed /tmp/debconf-seed" causes /media to be mounted & not unmounted
[18:42] <directhex> looks like a change joeyh made in debian-installer-utils (1.98)
