[arch-releng] [PATCH] [configs/*] chroot to root-image for initramfs build

Avoid issues with -b BASEDIR (*). We became independent of the mkinitcpio version of the build environment.

[arch-releng] [RFC] Improvements in PXE boot (add HTTP/FTP support)
by Gerardo Exequiel Pozzi 22 Nov '11

22 Nov '11

Tested and worked fine both HTTP/FTP on differents servers. Feedback is welcomed! There is no resolver on initramfs so only IP is supported (at least for now). Note 1: This work is in a branch that uses mount from util-linux (mkinitcpio-git) Note 2: Due some issue in mkinitcpio in add_binary() you need curl installed in build enviroment. :: Running Hook [archiso_pxe_common] IP-Config: eth0 hardware address 52:54:00:12:34:57 mtu 1500 IP-Config: eth0 guessed broadcast address 192.168.0.255 IP-Config: eth0 guessed nameserver address 192.168.0.218 IP-Config: eth0 complete (from 192.168.0.218): address: 192.168.0.90 broadcast: 192.168.0.255 netmask: 255.255.255.0 gateway: 192.168.0.218 dns0 : 192.168.0.218 dns1 : 0.0.0.0 rootserver: 192.168.0.218 rootpath: filename : :: Running Hook [archiso_pxe_nbd] :: Running Hook [archiso_pxe_curl] :: Getting info of 'http://192.168.0.218/archlinux-2011.11.21-netinstall-i686.iso' :: Mounting /run/archiso/pxe_curl (tmpfs) filesystem, size='201326592' :: Downloading 'http://192.168.0.218/archlinux-2011.11.21-netinstall-i686.iso' % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 192M 100 192M 0 0 141M 0 0:00:01 0:00:01 --:--:-- 141M :: Mounting '/dev/disk/by-label/ARCH_201111' to '/run/archiso/bootmnt' :: Device '/dev/disk/by-label/ARCH_201111' mounted successfully.

[arch-releng] PXEboot + unattended install
by Greg Sutcliffe 20 Nov '11

20 Nov '11

Hi all, Apologies if this has been covered before - I've been Googling for the few days, and found a lot of info on both of these topics - but not both together. As far as I can see, it's possible to boot an ArchLinux install instance over PXE (using the archboot project). I've managed to get that working just fine. I also understand that it's possible to pass a prewritten script to AIF to handle the actual install (and potentially the post-install steps?). I've not actually tried to write one of these yet, but it's next on my todo list. It seems the last tiny link to integrate the two is missing - I cannot find any documentation on how to get the installer to automatically execute an AIF script. I did find a slideshow (http://goo.gl/6I8QP) which on Slide 13 states this integration is a "Missing Feature" - is that still the case? As a bit of background (since this is my first post to the list) - I'm working heavily with Foreman (www.theforeman.org) which is a provisioning system for automatically deploying and installing machines. Since I'm a keen Arch user, I'm trying to add Arch support to Foreman. I have now added the PXE side of things (which works great), and I'm more than happy to help write/test any solutions to the above problem, since I can now re-image (via PXE) my Arch hosts with about 4 clicks in Foreman's interface :) Looking forward to learning more about this :) Cheers, Greg
