Right. I'd forgotten about hosts. Could you try the attached patch to the postinst? I've also attached the full file in case you can just copy it onto the system. This patch should make ppp-udeb generate the hosts file the same as netcfg does for systems with dynamic IP. Please try with both a set and an empty domain name. > > Note also that for normal netcfg, D-I basically works the same way when > > dhcp is used: if the domain name is entered manually, it is ignored. > > See for example #328646. > > But isn't this considered to be a bug? I'm not sure as I'm not enough of a networking expert. It probably does not really make sense to fix it in d-i as long as dhcp-client remains as it is.
