On the other hand, including a customized preseed file in a setup CD will allow for more automation, but requires re-mastering of the CD. The configuration of domain and host name, and keymap are still being asked, even if you have them in your preseed file as shown above. So if you want to kickstart the preseeded installation without a single questions asked, append the following more options to kernel boot prompt: console-keymaps-at/keymap=us hostname=myhost domain=example.com locale=en_US Perhaps David Heller can throw some light on this and let us know if its bug. == Comment: #2 - Edward R. Cheslek <eches...@us.ibm.com> - 2015-04-29 07:57:29 == I'm booting and installing from the network. Even if I leave the hostname related options out of my preseed, it still picks up and displays the correct hostname from dhcp. == Comment: #3 - David Heller <helle...@us.ibm.com> - 2015-05-05 14:12:52 == I'm not very familiar with this particular preseed option so I'm not sure how it's supposed to behave. However, in a quick test on Ubuntu 15.04, adding "netcfg/hostname=blah" to the kernel cmdline worked: it successfully overrode the hostname from DHCP (the way it is usually set in my environment) with no other changes required. In the preseed however, I could not make it work, even if I commented out the related lines: #d-i netcfg/get_hostname string unassigned-hostname #d-i netcfg/get_domain string unassigned-domain d-i netcfg/hostname string blah And looking in the installer log, it could be a order of operations thing, since we see it picking up the hostname from DHCP before retrieving the preseed... # cat /var/log/syslog | egrep "hostname|seed" May 5 16:10:16 netcfg[2270]: INFO: DHCP hostname: "myhost" May 5 16:10:16 netcfg[2270]: DEBUG: Preseeding domain from global: ibm.com May 5 16:10:16 main-menu[301]: INFO: Menu item 'network-preseed' selected May 5 16:10:18 preseed: successfully loaded preseed file from ftp://9.114.211.201/install/autoinst/myhost That said: this doesn't tell exactly when the hostname was *set*, or if it should be overridden even if it is set at that point. IMHO it should work the same way in the preseed as it does command-line, regardless of order, since that is what the user is requesting. If the installer already "set" the hostname from DHCP info, well, it should set it again with what the user wants. But I don't know if this is supported or expected to work in all cases. Frankly, I'm not even sure if this is the correct way to do it in preseed (although it seems like it is). But I think it's fair to mirror this to Ubuntu to ask. == Comment: #5 - Edward R.
