It is. However that patch would need to be redone against Matt's changes
to netcfg.
Attached a new one, so that excuse can no longer be used.

Bug#681801: Preseeding console-keymaps-at/keymap=us no longer works to select keymap
Package: console-setup-udeb Version: 1.80 We perform automated preseeded Debian installations. With Debian Squeeze we are able to use the following boot parameters to prevent Debian from prompting for country and keyboard settings: == debian-installer/locale=en_US kbd-chooser/method=us console-keymaps-at/keymap=us == However with Wheezy this no longer works, and we get prompted for keyboard map regardless (screenshot: http://s17.postimage.org/on6is922n/keymap_prompt.png ) In case a different preseed value then console-keymaps-at/keymap=us is necessary nowadays, please update the documentation ( http://d-i.alioth.debian.org/manual/en.amd64/apbs04.html#preseed-l10n ) -- Yours sincerely, Floris Bos -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe.

Re: preseed doesn't overwrite existing lvm partitioning

I have a preseed configured and it will install on virgin hardware without problem. But if I run the same install procedure for a second time on the same machine, I keep getting no root partition errors from the partitioner. Noticed that as well. Currently use the following ugly workaround to get the first disk (on some systems it is not /dev/sda) and remove LVM stuff: d-i partman/early_command string debconf-set partman-auto/disk $(list-devices disk | head -n1) ; pvremove -y -ff `list-devices disk | head -n1`* || true (To get it more foolproof, you might also need to check other disks in the system for the presense of lvm volume group names that might conflict with what the installer wants to use) -- Yours sincerely, Floris Bos

And ideally it should not just be a partman option, but a global option to assume sensible defaults for an unattended installation so that does not stop until an error is really fatal. Now you need to set about 50 preseed options to get a more or less flawless fully automated installation. While I suspect that a large number of users only want a custom root password and a custom network configuration, and could live with defaults for everything else... Yours sincerely, Floris Bos

Re: About using static config with pxeboot/preseed
Hi, On 11.10.2011 17:17, Julien Escario wrote: I'm trying to configure full automated install. The server is booting over pxe, get his dhcp lease and retrieve the preseed file over http. Preseeding is working well but not for the net config : ip address, hostname, ... After reboot, dhcp is still used and hostname is 'debian'. Is this a normal behaviour ? No way to use DHCP to get the address for d-i and install the server with a static address ? Yeah, we noticed that as well. In our provisioning software (noc-ps) we simply work around that by not specifying the configuration in the preseed file, but feeding a static network configuration through kernel parameters: == netcfg/disable_dhcp=true netcfg/get_ipaddress=$ip netcfg/get_netmask=$netmask netcfg/get_gateway=$gateway == Regarding hostname: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=606636 Yours sincerely, Floris Bos -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe.
